"He has no idea the devastation he causes as he walks through the set," says Robert Luketic, who directed Luke Wilson in last year's Legally Blonde
. "I had to get these people back to work. I'm like, 'He's taken!' He's always dating somebody lovely." Those lovelies have included past costars Drew Barrymore
) and, most recently, Gwyneth Paltrow
(The Royal Tenenbaums
), but these days Wilson, 30, is a self-anointed "bachelor," who is content to kick back in the L.A. home he shares with his chocolate Lab Ted and mutt Brother or go on 4-mile beach runs. "Sometimes right after I've had some coffee, I'll get a little jangled and make myself jog," says the 6-ft. Texas-born actor, who doesn't seem the lady-killer type. "He's quiet and kind of shy but very much a gentleman," says Charlie's Angels
costar Cameron Diaz
. "I think he's very comfortable with himself." He sure dresses for comfort—jeans and khakis—probably a holdover from years of inheriting hand-me-downs from his brothers, actor Andrew, 37, and actor/screenwriter Owen, 33 (who cowrote and appeared in Tenenbaums). For now, Wilson uses only sunscreen and moisturizer but wouldn't mind a little extra pampering. "I've got the time," he says. "I just don't have the masseuse!"
