Avril Lavigne is moving on from her failed marriage to Deryck Whibley - she's reportedly dating The Hills star Brody Jenner.

The Sk8er Boi hit-maker filed for divorce from her husband of three years in 2009, citing "irreconcilable differences."

And Lavigne has bounced back from the split by embarking on a romance with The Hills hunk, according to E! News.

A source tells the website, "They're hooking up, but they're keeping it low-key. You can tell they're into each other and both like to have a good time. They're cute together."
