PDA alert!

Kellan Lutz showed up with his girlfriend, actress Sharni Vinson, to the premiere of his new film "Immortals" Monday night, and the pair didn't hold back with their public displays of affection.

After Lutz finished posing for red carpet photos and signing autographs for fans, he headed over to lock lips with Vinson.

The actor, who previously dated "90210" star AnnaLynne McCord, was first linked to Vinson back in July.
