Deryck Whibley listened to Paris Hilton cry after she found out her sex tape was being leaked.
The Sum 41 frontman - who previously dated the 43-year-old socialite in 2003 - has recalled the emotional moment she found out her ex was planning to leak the intimate video, and she turned to her former flame for support.
Writing in his book 'Walking Disaster: My Life Through Heaven and Hell', he said: "She was doing everything she could to stop it from coming out, but six or seven months after we broke up, the s*** hit the fan.
"We had stayed in touch after we split, and after the tape came out, I reached out. We had some sad conversations and I listened to her cry about having to tell her parents about it."
However, the 'Still Waiting' rocker praised the reality TV star for turning the traumatic experience into "something that worked for her".
He added: "She's a smart person, though, and it was great seeing how she was able to turn that invasion of privacy into something that worked for her in the long run.
"Her advocacy is admirable, too. She definitely knew how to be the Mac. And most importantly how to stay the Mac."
In her own memoir last year, Paris reflected on the fall-out of the tape, and how she felt like her "life was over" when it was leaked.
She wrote in 'Paris: The Memoir': "The world thinks of me as a sex symbol, and I'm here for that, because symbol literally means icon.
"But when people saw that sex tape, they didn't say 'icon,' they said 's***.' They said 'w****'...
"I felt like my life was over, and in many ways it was. Certainly, the career I had envisioned was no longer possible."
Paris has become a huge success as a DJ, reality star and more, and she is now married to Carter Reum, who has helped her rediscover her sexuality.
She told Harper's Bazaar magazine: "It wasn't until Carter that I finally am not that way. I enjoy hooking up with my husband.
"I just feel like after all the hell I've been through, I'm finally getting what I deserve, which is someone I can trust and someone to build a real life with."
