Tulisa Contostavlos has revealed she was so distraught after a sex tape of her appeared online she slept on the floor for a week.
The X Factor judge and N-Dubz star took legal action after footage surfaced of her sharing an "intimate moment" with former boyfriend Justin Edwards, who denies posting the clip.
Tulisa, 23, said she was "devastated" by the tape's release and became a prisoner in her home.
In an interview with the Guardian, she said: "I slept on the bathroom floor for seven days ... I just wouldn't go out of the house. Couldn't sleep. Didn't really want to eat anything.
"But I snapped out of it. I knew what I was doing. I knew in my head that I was depressed; I knew why I was depressed. It was all logical. I didn't want to smile. I didn't want to be happy. I needed to have my tears and tantrums, my bad moods, and get myself into a state to come back out of it.
"And I literally just woke up one morning, as happy as Larry, put on my best dress, make-up, full hair: 'OK, I'm going out'."
Tulisa spoke out after the tape appeared by recording her own response and posting it on YouTube.
She said she didn't feel she had done anything wrong and that many young women behaved far worse.
Tulisa - who confirmed in an interview earlier this week she would be returning to the X Factor - said: "There are probably girls out there who have done a million times worse with their boyfriend, and are probably going to go out tonight and get laid with a random bloke they've just met, whereas I'll meet a bloke and make him wait six dates before he even gets a shag."
