Co-Star Spills Robert Pattinson’s Girl-Getting Secrets

Kellan Lutz plays British heartthrob Robert Pattinson’s brother in Twilight, giving him a lot of behind the scenes access to what makes the star tick- and what about him really makes the girls go wild.

Calling into Ryan Seacrest’s radio show on Friday, Lutz happily played along with the radio host’s comment about being the “better-looking Cullen” but quickly switched gears to discuss Pattinson’s unmistakable appeal.

"His accent and his crazy hairdo get the girls swooning," Kellan told Seacrest. But the actor’s secret weapon lies in how he never actually wants to be the center of attention.

"Rob's kind of shy, and he does this thing, when he's really shy, or when someone asks him something, he lowers his head down and the girls love it!" Lutz revealed.

"He's such a humble guy," he continued. Even though Pattinson is his biggest competition for adoration of female fans worldwide, Lutz admits: “I’m very impressed with him.”
