OMG!!!!! it' too sad for derick...

it' all about avril and derick..Court records show Avril Lavigne has filed for divorce from her musician husband after three years of marriage. Lavigne filed for divorce from Sum 41 singer Deryck Jason Whibley on Friday in Los Angeles.

The couple were married in July 2006 and have no children together. Lavigne cited "irreconcilable differences."

The 25-year-old punk-pop singer burst to fame with her 2002 debut album "Let's Go."

Lavigne is asking a ruling to block Whibley from receiving spousal support.

Court records show Whibley was granted a request to add Lavigne's last name to his name in December 2007. After three years of marriage, Avril Lavigne and Deryck Whibley have split.

"She dumped him and told him she was leaving him. She wants to move on," a source tells the new Us Weekly, adding that Lavigne, 25, forced him out of their $9.5 million, 12,00-square-foot estate in L.A.'s Bel Air. "Divorce papers will be filed any day now."

Things are about to get "Complicated" for Avril Lavigne and hubby Deryck Whibley. Sources close to the couple, who have been married since 2006, say they're headed for Splitsville.

That seemed apparent when the Canadian songstress was out and about in Southampton last weekend - sans hubby and looking anything but married.

Avril Lavigne Confirms: "Deryck and I Are Separating"

"Deryck and I have been together for six and a half years," she wrote. "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. 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."
