Don't couples ever stay together anymore?

While his Marley & Me co-star is getting serious with John Mayer, People reports that Owen Wilson has finally called it quits with on-and-off girlfriend Kate Hudson.

One of Owen's friends calls it a "pretty bad breakup" and that Owen "wants to put it behind him." But is this the end of their relationship for good?

In other breakup news, singer Shania Twain just split from her husband - music producer Robert "Mutt" Lange - after 14 years of marriage. Damn, wonder what happened there!
