A growing number of famous names have ditched celebrity convention to tie the knot in low-key style, whether that's with their beaus in town halls (Keira Knightley) and even their homes (Jennifer Lopez).

There's something remarkably spontaneous and sentimental about this group of non-starry weddings. Take a look below.

Kristen Bell and Dax Shepard, 2013

When Gossip Girl star, Kristen Bell married her partner, actor Dax Shepard in 2013, she didn’t share any of the pair’s wedding pics.

But three years later – in 2016 – Bell gave CBS Sunday Morning viewers a sneak peek into their nuptials.

The pair opted for ultra low-key for their wedding – which cost only $142 US (£108) getting married in the local courthouse. Bell wore a simple black top with black trousers and Shepard, a classic suit.

The 36-year-old Frozen star told the CBS presenters:

 “We got married in a tiny room in the Beverley Hills courthouse, and it was still one of the best days of my life.”

The touching images show the couple exchanging their vows, signing their wedding papers and finally, having their first kiss as a married couple.

Now that’s how to perfect a low key wedding.

They share two daughters – Lincoln, three and Delta, 18 months. 

Scarlett Johansson and Romain Dauriac, 2014

Just months after the birth of their daughter Rose, Scarlett Johansson and her fiancé Romain Dauriac are said to have tied the knot in a secret ceremony.

The 30-year-old actress and her French journalist partner, 31, exchanged vows in an undisclosed location in the States, according to a report in the New York Post. 

“Scarlett and Romain were married in a very intimate ceremony after the birth of their daughter,” a source told the newspaper's Page Six section. “They kept the wedding a big secret because they both wanted privacy.”

The couple had originally intended to marry in Dauriac's native Paris, where they are based, but they eventually chose a remote U.S. location - away from both Hollywood and Johansson's home town of New York.

A secluded and natural venue in a state such as Colorado was suggested as the possible location for the ceremony, by the source who spoke to the Post.

There's been no confirmation yet on the marriage from Johansson's rep but the Lucy star was photographed at a fundraising event in New York in November, wearing what appeared to be a wedding ring alongside her vintage Art Deco diamond engagement ring (above left).

Johansson and Dauriac began dating in November 2012,  a year and a half after Johansson divorced her husband of three years, Ryan Reynolds. They got engaged last year and the actress fell pregnant in January.

"He’s my buddy," she has previously said. "Being engaged is an exciting time to enjoy and to really savour."

Olivia Palermo and Johannes Huebl, 2014

Understated elegance was the theme of the day as socialite Olivia Palermo, 28, got wed to her boyfriend of six years, Johannes Huebl, in a park in the leafy town of Bedford in New York state this weekend.

The bride chose a simple cream cashmere sweater with scattered ostrich feathers and chic white shorts with a full tulle skirt overlay, all custom-made in a stylish and unique three-piece by Carolina Herrera.

Her hair and make-up was similarly low-key. The City star opted to pull her locks back and up in her signature centered-part ponytail, paired with natural-looking makeup.

"I wanted the makeup to be light and fresh and more focused about the lashes while keeping the eyes clean. My hair was in an un-contrived ponytail, one of my favorite personal looks," Palermo wrote on her blog.

The groom wore a bespoke tailored white Marc Anthony Hamburg suit with a Marc Anthony Hamburg piquet shirt, a navy Charvet tie and navy Etro pocket square.

We particularly love the way Palermo finished off her look with a gorgeous pair of deep blue Manolo Blahniks, as the final flourish:

Both Palermo and Huebl, who have dated for six and a half years, wanted to keep their ceremony low-key and stylish. They said their vows in front of just a handful of family members and closest friends, surrounded by ivy and blossoming flowers of the surrounding park.

"We really wanted to keep this beautiful day very private and special to us and enjoyed the whole day with our family and two friends. Bedford is such an amazing and romantic countryside," the happy couple said.

Keira Knightley and James Righton, 2013

Despite being one of Britain's biggest actresses today, Kiera Knightley and beau, James Righton, singer and keyboard player with pop band Klaxons, slipped into a town hall in the hilltop village of Mazan in the south of France and exchanged their vows. Instead of saving their pictures for a magazine exclusive, the pair skipped down the sun-drenched streets with daisies in Knightley's hair and the moment was captured for the world to see.

Fashion commentators celebrated Knightley's thrifty approach to her dress - a pink Chanel number she already had hanging in her closet (pictured above). The star said, "I'd worn the dress lots. It was my something old. And I liked not making a big deal about it. I just wanted to be in something I had had a great time in, something I would have a great time in again."

The pair managed a second secret wedding ceremony in the woods soon after their civil ceremony.

Dawn O'Porter and Chris O'Dowd, 2012

The couple ditched luxury marquees and historic cathedrals for a rather unconventional setting - the house The Kings Speech was filmed in, a 1775 London townhouse on Portland Place.

Whilst watching the film, the actress revealed the location of her wedding on Twitter saying: "This is the house we got married in."

"Even THAT sofa was there," O'Porter continued. "It literally was exactly the same. Ahhhh the memories."

Their celebrations were notably laid-back with the newlyweds wearing matching onesies and hosting an informal three-day party they called "WedFest".

Beyoncé and Jay Z, 2008

Mr and Mrs Carter are one of the highest-earning celebrity couples ever, with an estimated combined income of $95 million (£56 million) last year. But the couple are notoriously private about their relationship and their wedding was no exception.

The ceremony was said to have taken place in Jay-Z’s New York apartment.

"It happened earlier this evening. Jay wanted it to be a really private affair — close friends and family," a source told People magazine at the time.

Guests included Coldplay's Chris Martin and Gwyneth Paltrow, and Beyoncé's former bandmates in Destiny’s Child, Kelly Rowland and Michelle Williams

We were treated to a glimpse into the ceremony - which is still a heavily guarded secret - in Beyoncé's music video for I Was Here, which featured a video of the star trying on her bridal gown, designed by her mother, Tina Knowles.

Kate Winslet and Ned Rocknroll, 2012

When Kate Winslet married for the third time it was so inconspicuous, even her parents didn't know about the nuptials. The Oscar-winner wed Ned Rocknroll in a low-key ceremony in New York, with a few friends and family and her two children present.

However, Winslet's Titanic co-star Leonardo DiCaprio was there to walk the bride down the aisle and give her away.

Rachel Weisz and Daniel Craig, 2011

Before Rachel Weisz and Daniel Craig tied the knot in secret, they hadn't even confirmed they were an item. The pair wed in New York with just their two children and two witnesses present.

"When I turned 40 it was one of the best years of my life; I played Blanche in A Streetcar Named Desire, Hester Collyer in The Deep Blue Sea and got married – none of which I’d ever done before," Weisz later said.

"Someone called us a power couple the other day," Bond star Craig quipped. "I was like, what the f**ck does that mean?

"We just keep ourselves to ourselves."

Jennifer Lopez and Marc Anthony, 2004

Jennifer Lopez stunned the showbiz world by getting hitched to singer Marc Anthony in a unexpected and casual ceremony at her Beverly Hills home back in 2004.

The singer and actress invited everyone to her house for an afternoon party, but at 6:22pm, Lopez appeared walking across the backyard in a bridal gown and holding a white umbrella. The surprised guests quickly got into the mood of events by clapping and cheering.

Sarah Jessica Parker and Matthew Broderick, 1997

These two got wed in secret event with many of their 100 guests thinking they were attending a party, only to find it was a wedding when they arrived. The ceremony was held in the Angel Orensanz Foundation Center (formerly a synagogue) in New York and Broderick's sister, the Episcopal Minister Janet Broderick Kraft, officiated.

In keeping with the low-key event, Broderick’s suit was off-the-rack and Parker wore a black dress designed by Morgane Le Fay.

Britney Spears and Kevin Federline, 2004

Britney Spears and backup dancer Kevin Federline scrapped their original plans for a lavish wedding at Santa Barbara's Bacara resort in favour of a surprise ceremony for just 27 friends and relatives (guests were invited to an engagement party, but it turned out to be their actual wedding).

The couple dressed the bridesmaids and groomsmen in personalised matching Juicy Couture tracksuits that were embroidered at the back with "The Maids" for the women and "Pimp Daddy" for the men. Their celebrations were topped off with a night of clubbing.

"It became this huge thing and I was like, 'What are we waiting for?" said Spears to People magazine. We know this is the real thing, why not just do it now? That's why I wanted to sneak and do it our little way."

Pamela Anderson and Kid Rock, 2006

The Baywatch star and musician Kid Rock took to the Saint Tropez seas for their free-spirited wedding in 2006. Anderson ditched conventional bridal attire for a white string bikini and matching veil while Rock opted for a matching T-shirt.

The model and actress described her discrete (and legally non-binding) nuptials as, "the best most romantic wedding of all time", and followed it up with a series of ceremonies in the US.

"I'm going to get married a few times this month to the same guy," she later said, during a news conference in Las Vegas.

"We had to do Malibu, we've got to do Detroit, and we've got to do Nashville."
