Avril Lavigne and Tyga Call It Quits

Back in March Canadian rocker Avril Lavigne ended her engagement to alt-rocker Mod Sun to date West Coast rapper Tyga [click here if you missed that].

They said it wouldn't last, and it didn't...

From TMZ

Sources tell us the two musicians -- who went public with their relationship in March -- recently went their separate ways ... having split a couple weeks ago. We're told it was a mutual decision, and that there are no hard feelings -- the romance just ran its course.

Avril just came off her tour, and Tyga's in the middle of making new music.
