Simple Plan star CHUCK CORNEAU has taken the ultimate revenge on his ex-girlfriend - he has written a song about her infidelity.
The rocker admits the band's latest track Your Love is a Lie is based on his relationship with a cheating partner - who he is refusing to name.
He tells, "It's a song about falling in love with someone and being surprised and very disappointed that they'd do something like that to you when you give them your heart.
"I think a lot of people feel very betrayed. We wrote a song and it feels good to write about it, because at the time that's all I could think about.
"During the moment we were writing the song, it was happening. I'm okay now. Writing the song helps."
