Singer Avril Lavigne is divorcing Deryck Whibley, the frontman for band Sum 41, after only three years of marriage.

“She dumped him and told him she was leaving him. She wants to move on,” a source revealed to Us Weekly, and also added that Lavigne, 25, forced him out of their $9.5 million, 12,000-square-foot estate in L.A.’s Bel Air. “Divorce papers will be filed any day now.”

Whibley, 29, “is crushed,” adds another insider.

Avril wrote on her MySpace confirming their split saying:

“Deryck and I have been together for six-and-a-half years. We have been friends since I was 17, started dating when I was 19, and married when I was 21. I am grateful for our time together, and I am grateful and blessed for our remaining friendship,” the message reads. “I admire Deryck and have a great amount of respect for him. He is the most amazing person I know and I love him with all my heart. Deryck and I are separating and moving forward on a positive note.”

Lavigne concluded the message by thanking her family, friends and fans for their support.
