Ex-Love Island host Caroline Flack has been found dead in her London flat aged 40.
A lawyer for the family said the star had taken her own life.
She was due to face trial in March over allegations that she had assaulted her boyfriend, which she denied.
A family statement read: "We can confirm that our Caroline passed away today on the 15th February.
"We would ask that the press both respect the privacy of the family at this difficult time."
Flack's last Instagram post came on Friday, a day before her death – and showed her giving her pet dog Ruby a kiss.
A day earlier she wrote: "I'm going to speak today... mine and my family's life is no longer up for entertainment or gossip."
But a source said she wrote the post "without thinking" and changed her mind.
Eamonn Holmes said in a tweet he was "shocked beyond belief".
Phillip Schofield paid tribute on Instagram. He wrote: "You poor darling girl my heart is breaking #BeKind".
Davina McCall also responded to the tragedy.
She tweeted: "I'm so so sad to hear about @carolineflack1.
"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."
Jack Whitehall says her death is "utterly devastating", adding she was a "fun, kind and beautiful" person.
Utterly devastating about Caroline Flack. She was a fun, kind beautiful person, always loved seeing her. So unfair that this has happened. Let's pray we learn from this and remember to be a little bit more compassionate to people when they are down.
