Lily Allen has been targeted by social media trolls after revealing that she suffers from post-traumatic stress disorder (PTSD) following the stillbirth of her son in 2010.

The 31-year-old singer had originally taken to Twitter to highlight the prejudice shown towards immigrants.

But, when anonymous users began firing abuse at Allen and accusing her of having mental health issues, things began to get nasty.

“I do have mental health issues,” she said, before going on to reveal that she has been diagnosed with PTSD, postnatal depression, and bipolar disorder.

One Twitter user, taking note of her remarks, responded: “Can I just ask, how did you get PTSD?”

Allen was quick to reply to the message, explaining that she had suffered a severe psychological shock when she lost her baby son six months into her pregnancy.

Allen soon found her social feeds flooded with inflammatory tweets, with one reading: “Not to be a d**k, but I very highly doubt it was 10 hours.”

This prompted Allen to respond: “You are a d**k. And it was. I was there, you weren’t.”

Another troll tweeted the Smile singer claiming that, if she hadn't taken drugs, “you wouldn't have miscarried.”

Lily replied: “I didn't miscarry, I went into early labour and my son died from his cord wrapped round his neck.”

One of the most shocking tweets suggested: “The baby knew you were going to be such a horrible mother.”

The onslaught of abuse has convinced Allen to take a step back from Twitter.

“My timeline is full of the most disgusting, sexist, misogynistic, racist s**t,” she wrote. “Really, new levels. I’m no masochist, so I’ll be back.”

It was later revealed that control over Allen’s account had been handed over to a friend called Dennis, who announced that he was going on a “hate blocking spree”.

Allen, who has two daughters aged five and four with her former partner Sam Cooper, previously opened up about the stillbirth of her son in 2014.

Sitting down on The Jonathan Ross Show, she said: “I think it's difficult for anybody regardless of what world they live in and actually what I took home from that experience was.

“Even though it was the most unfortunate thing that can ever happen to a person, I was very fortunate in the sense that I have a loving partner to go home to and share that experience with.”

Allen went on to add:  “There are many women - [there are] 17 stillbirths in the UK everyday - that go home and they don't have that support, they have to go home and deal with that on their own so I am kind of in a bit of a - since that happened - in a count my blessings scenario rather than feeling sorry for myself.”
