Avril Lavigne Dating Brody Jenner?

Drum roll, please! Avril and Brody Jenner are definitely an item!

For the past several months. Avril Lavigne has been spotted out with two different guys: Brody Jenner and Wilmer Valderrama. And although the punk-pop princess was spotted out with Wilmer, 30, on Valentine's Day, HollywoodLife.com can officially confirm that she's made her choice - and it's Brody!

The two were all over one another at the grand opening of Drais nightclub in Hollywood March 17, and it's clear that neither Avril, 25, nor Brody, 26, are keeping their relationship under wraps anymore!

HollywoodLife.com spotted the duo sitting in a booth next to one another for the entire night, whispering into each other's ears and getting very cozy. Wearing matching green T-shirts in honor of St. Patrick's Day, Brody even gave Avril's derriere a gentle squeeze before sharing a quick kiss. Adorable!

The cozy couple also had a shocking table companion - none other than Avril's OTHER reported love interest, Wilmer! But it's clear the three are all just friends: while sipping vodka cocktails, the three chatted and hung out like besties. We can report that Wilmer didn't look jealous AT ALL - especially given that Avril and Brody seemed to be in their own little world.

We think that The Hills hottie and his punky pop singer girlfriend make an adorable pair! What do YOU think?
