Avril Lavigne and Deryck Whibley have reportedly split.
Avril is said to have asked Deryck, who she wed three years ago, to move out of their Los Angeles mansion after calling time on their relationship.
A source told Us Weekly magazine: "She dumped him and told him she was leaving him. She wants to move on. Divorce papers will be filed any day now."
Sum 41 rocker Deryck is apparently "crushed" by Avril's decision, and was keen to work through their problems.
Avril, 24, is so determined to move on from the relationship she has decided to ditch the tracks from her forthcoming album which she worked on with Deryck.
A friend told the publication: "She is going to do new songs that don't have his mark on them. She wants no trace of him."
Rumours the couple's marriage was in trouble have been circulating for months, 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 not present when Avril showed her new clothing collection at New York Fashion Week on Monday.
Deryck's representative did not comment on the report, while Avril's could not be reached.
