Kellan Lutz was notoriously tight-lipped about his longtime romance with on-off girlfriend AnnaLynne McCord. But when it comes to his new love Sharni Vinson, the 26-year-old Breaking Dawn actor can't say enough good things.

"I'm very happily with someone," Lutz said on Ryan Seacrest's KIIS-FM radio show Friday. "She's a happy person, which really just clicks with me. It's just great to have someone you can smile with all the time. It's really special."

Vinson, 28, was equally effusive when she spoke to Australia's Herald Sun at the Immortals premiere on Monday.

"We met in a chemistry reading for Step Up 3D. We kind of were doing our own thing and not in touch, and then he got in touch and I was like, 'Hey,'" the actress recalled. "We are really happy."

Vinson also joked that she inspired her famously buff beau to try a "new workout."

"He does his push-ups with one hand holding me," she laughed.
