Pop star Avril Lavigne has split from Kim Kardashian's half-brother Brody Jenner, according to reports.
 
The reality TV star and pop punk Lavigne have been dating since shortly after she split from her husband, Sum 41 rocker Deryck Whibley at the end of 2009, but now editors at Life & Style magazine claim the stars have gone their separate ways.
 
According to the publication, they were divided on their views of marriage.
 
A source tells the magazine, "They decided to end their relationship... 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."
 
Lavigne and Jenner have yet to comment on the split reports.
