UPDATE: You can read Avril’s personal note on the divorce here.

Whispers about a possible split have just grown louder. It’s now being reported that divorce papers will be filed shortly for Avril Lavigne and Deryck Whibley.

Avril is said to have asked Deryck, whom she wed three years ago, to move out of their Los Angeles mansion after calling time on their relationship. “She dumped him and told him she was leaving him. She wants to move on,” a source told Us Weekly magazine.

The Sum 41 rocker is apparently “crushed” by his wife’s decision and was hoping to work through their problems.

Avril, 24, is so determined to distance herself from the relationship that she has decided to ditch tracks she worked on with Deryck from her upcoming album. “She is going to do new songs that don’t have his mark on them. She wants no trace of him,” a friend told the magazine.

The couple’s marriage has reportedly been in trouble for months now, with Avril often seen partying with friends without her husband. In June, Deryck went to the Los Angeles premiere of Transformers: Revenge of the Fallen alone while Avril spent a week holidaying in Saint-Tropez with pals.

Deryck, 29, was also not present when Avril showed her new clothing collection at New York Fashion Week on Monday. Whibley’s representative did not comment on the report, while Lavigne’s could not be reached.
