Is there anything sexier than a half-naked Robert Pattinson?

The actor, 25, went paddle boarding in Malibu, Calif. Friday. The bearded star, who hasn't been photographed shirtless since shooting The Twilight Saga: Breaking Dawn – Part 1 in St. Thomas in April 2011, also went jogging along the coast.

The sunny spot is much different than Pattinson's native England, but a source close to the actor tells Us Weekly that "he really likes Malibu. He and Kristen [Stewart] spend all their time there."

It's also made it easier for Pattinson to get serious about his fitness. "He has been trying to get more outdoorsy and cut down on smoking and drinking," the source tells Us, adding that he's been "doing more athletic stuff." See more photos of Robert Pattinson paddle boarding.

Though they'd been spotted at Chateau Marmont and Hotel Cafe earlier in the week, Pattinson didn't join girlfriend Stewart, 21, at Saturday's Nickelodeon Kids' Choice Awards. Stweart, who wore a blue Stella McCartney dress, won Favorite Movie Actress.

Pattinson's next film, Cosmopolis, hits theaters May 23. It also stars Jay Baruchel and Paul Giamatti.
