Singer Frankie Bridge revealed she was left feeling "frightened" and "lonely" after receiving death threats on social media.
The 27-year-old, who is one fifth of girl band The Saturdays, admitted that she could not even bring herself to tell her husband, former footballer Wayne Bridge, about the online trolling she endured.
Speaking to Gaby Roslin on ITV's Lorraine, Frankie admitted, "I think I was very lucky when I started my career, there wasn't really any social media so I never had to deal with that.
"I think it was a big eye-opener when I came into The Saturdays and it's even grown since then.
"I've had some really nasty comments, things about my weight, past relationships or whatever, death threats."
When asked whether she turned to Wayne for support, she confessed: "It just really frightened me, really. I didn't really tell anyone about it.
"Because it's online I just thought, 'Oh, what can you do about it?'
"I think that's the worst thing, it does make you feel quite lonely and that there's nothing you can do about it."
Bridge is presenting a documentary on Channel 5 about internet trolls and said she would want to know why her abusers send her such vile messages.
She also spoke about her desire to do tough reality show I'm A Celebrity...Get Me Out Of Here! before she became mum to sons Parker, two, and Carter, one.
Frankie, who came runner-up on Strictly Come Dancing in 2014, said: "It was the one other show that I always said I would maybe do, but I would be awful on it. I would absolutely hate it. But I would want to do it purely to push myself to try and see how I would react.
"But now I have got the boys, I don't think I would want to. It's like three weeks of not even being able to know how they are and I think if it was a few years ago I might have given it a go but it would be the complete polar opposite to Strictly!"
