BJennerALavine080910-500.jpgAfter two years together (not to mention getting their names tattooed on one another), Avril Lavigne and Brody Jenner have split.

"They decided to end their relationship," an insider dished to Life & Style. "It wasn't working out, and they wanted to go their separate ways." Another source tells the mag, "She wanted to settle down, but he wasn't exactly ready. They had been having problems starting in the summer with her tour because she was on the road all the time. It put a strain on their relationship."

Of course, a source for Us Magazine seems to suggest that Avril was to blame for the split, noting that Brody "felt held back by his girlfriend." The source said, "Every time he wanted to come back and take meetings to get his career back in order, she would make him go to Asia and Europe. He hasn't worked and he wants to. They were both unhappy because he wants to have his career, she wants him to stay with her." Apparently Avril vetoed multiple TV show offers Brody recently received, but there's still a chance the two could reconcile. "Brody is trying to set the ground rules and wants to be able to work," the source revealed. "They have to find a balance."

Avril began dating Brody just a few months aafter she split from then-husband Deryck Whibley, and rumors began to circulate that Avril and Brody were dunzo when she was spotted dining with Deryck in December. The last time we spotted Avril and Brody together was in November of 2011, after a bar brawl that resulted in the petite Canadian singer getting punched in the face.
