Though fans waved signs professing their "lust for Lutz," the dark-haired hottie only had eyes for one woman, Australian model Sharni Vinson.
Vinson was a vision in a floor-length strappy red gown, rivaling that of Kellan's bestie, Ashley Greene.
"My girlfriend?" Kellan smiled, when SheKnows quizzed him on his new love. "Yeah, she's here."
This is the second time in the past two weeks that Lutz has put his dating life on display. The actor stepped out with Sharni at the red carpet premiere of Immortals as well.
In his past relationships, like with 90210 actress AnnaLynne McCord, Lutz always remained tight-lipped. But it looks like Vinson is in a league of her own.
Kellan was clearly elated to be at the premiere with his new lady, telling SheKnows, "It's amazing. You just feel on top of the world."
So how is Lutz planning on celebrating the movie's success? The actor let us in on his big plans…
"I want to go to Vegas," Kellan laughed.
Sharni better keep a tight leash on this one!
