Nicole Appleton has revealed she had an abortion while she was engaged to Robbie Williams.
She is spilling the beans on her relationship with Robbie in her new autobiography Together with sister Natalie.
The former All Saint says she felt like killing herself after the abortion.
"What happened still lingers in my life. I want people to know what I went through," Nicole told the Daily Mail.
"After having my abortion I was in shock. I couldn't believe what I had done. I wanted to kill myself."
She said Robbie backed her decision to reveal details of her abortion and told her: "I'm so proud of you. You're so brave."
Nicole was twice engaged to Robbie before he ended the stormy 18-month relationship for good.
She is now engaged to Oasis frontman Liam Gallagher and has a 14-month-old son Gene.
The Appletons' book, called Together, is released later this year.
