AVRIL LAVIGNE & DERYCK WHIBLEY SPLIT.

Dun dun dun! After three years of Avril Lavigne being married to Deryck Whibley -- the two have split, according to US weekly.

"She dumped him and told him she was leaving him. She wants to move on," a source told the magazine. The source also revealed that Avril forced him out of their $9.5 million, home in L.A. "Divorce papers will be filed any day now," they said.

Another source told the mag that Deryck is "crushed" about the situation.  While I am surprised they lasted 3 years as most marriages in Hollywood don't -- most people saw this coming.

Avril had been spotted several times partying without hubby Deryck. Infact, the two are rarey photographed together.
