Caroline Flack, ex-Love Island host, has been found dead in her London flat, her family have confirmed.
A lawyer for the family said the star had taken her own life.
She stood down from the dating show after she was charged with assaulting her partner in December and was due to stand trial next month.
As well as presenting ITV’s Love Island she had co-hosted The X Factor and won Strictly Come Dancing in 2014.
The family said in a statement: “We can confirm that our Caroline passed away today, the 15th of February.
“We would ask that the press respect the privacy of the family at this difficult time and we would ask they make no attempt to contact us and/or photograph us.”

An ITV spokeswoman said: “Everybody at Love Island and ITV is shocked and saddened by this desperately sad news.
“Caroline was a much loved member of the Love Island team and our sincere thoughts and condolences are with her family and friends.”
Laura Whitmore, who took over presenting the show following Flack’s arrest, posted a picture of the pair on Twitter and wrote: “I’m trying to find the words but I can’t.”
TV host with popular appeal

As the Love Island host for four years, the winner of 2014’s Strictly Come Dancing and presenter of hit shows like The X Factor, Flack was one of the most in-demand and well-loved personalities on British TV.
Many fans grew up with her since her breakthrough co-hosting Saturday morning show TMi with Sam and Mark on CBBC in 2007.
From there, she went on to front Gladiators on Sky One, ITV2’s I’m A Celebrity… Get Me Out Of Here! spin-off and The Xtra Factor, before moving to The X Factor itself with Olly Murs in 2015.
Her charm and popular appeal made her an ideal choice when Love Island was relaunched in 2015, and she helped make it one of the biggest shows on British TV.
Her profile made her a fixture in the tabloids, and her relationships – including with One Direction star Harry Styles and rumours about Prince Harry – put her on the front pages.
But her career was in the balance after her arrest on suspicion of assault in December, leading her to be replaced on Love Island by Laura Whitmore.
Stars pay tribute
Love Island star Wes Nelson called Flack “an absolute diamond” and said he was heartbroken at the death of “one of the warmest funniest people I’ve ever met”.
Amber Davies, Love Island 2017 winner, tweeted: “My heart is actually broken.”
TV presenter Davina McCall wrote: “I don’t even know what to say. But my heart goes out to her friends and family x I might be a bit quiet tonight on social media .. just doesn’t seem right .”
Strictly co-host Tess Daly said: “Absolutely shocked and devastated at this tragic news. Rest in peace Caroline you beautiful girl.”
This Morning presenter Phillip Schofield paid tribute with a post on Instagram, writing: “You poor darling girl my heart is breaking #BeKind”.
TV presenter Jonathan Ross said he had been in touch with Flack recently and “had hoped she was doing better”.
“She was talented and smart and likeable and she will be missed. It’s awful,” he tweeted.
