After three years of marriage, Avril Lavigne and Deryck Whibley have split, Us Weekly reports in its latest issue (on newsstands now).

“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.”

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

Lavigne’s rep could not be reached; Whibley’s rep had no comment.
