The 34-year- old has often spoken about her difficult pregnancies with her two-year-old daughter, River, and baby son, Remington.

She said previously: “Nausea is for weak people. It was, like, hospitalisation. It's, like, bad. I had the worst pregnancies ever. I would end up in the hospital, dehydrated. People had to come to our house and I'd be on fluids.”

Clarkson - who is also stepmother to Blackstock’s older children, Savannah, 14, and Seth, 11 – also went on to explain that her career was also an important consideration when making the decision to undergo surgical birth control.

She said: “We're still working on [the balance]. It's pretty hard, being a working mum - I'm not going to lie - but it's worth it for not only my little girls, but our boys to see women working and still being able to do that and accomplish being a great mum, which I feel like I'm doing. I think it's worth it definitely.”

Clarkson added that she is grateful for her husband’s support, praising him for helping her to tackle the emotional side of parenthood, as well as for taking on his fair share of duties.

“I have a great teammate with my husband,” she said. “He will definitely reel me in when I'm like, 'It's all going down, we're losing it!'”
