"Whoo!" After five frames a frustrated Ludacris finally bowls a strike—much to the rapper's delight. "I love competing," he says, "and the best person to compete against is myself." So how is Ludacris (born Christopher Bridges) going to top his success in 2005, the year in which his acting career took off with acclaimed supporting performances in the indie hit Hustle & Flow and the Oscar-winning drama Crash? This month Ludacris, 29, introduces his latest album, Release Therapy, a mix of catchy, let-loose songs for the clubs and serious anthems reacting to issues like Hurricane Katrina. "I'm getting stuff off my chest, and I feel like a lot of people can relate to what I'm talking to," he says, adding that he included lighter fare to help "put your mind at ease."

What does the same for Ludacris? "I'm fidgety," he admits. "If I'm sitting around not doing anything, I feel guilty." So when he's home on his 22-acre spread near Atlanta, Ludacris challenges pals to go-kart races ("I always win—what can I say?") or pickup basketball games ("I can dunk ... if I lower the rim"). But his favorite pastime is hanging out with his 5-year-old daughter Karma, who often scales indoor rock-climbing walls with Dad. "She always has that look on her face like, 'I'm a little scared,'" he says. "But I'm always pumping her up for that reassurance that 'Daddy is going to make sure nothing happens to you.'" And when he's on tour, "we're so bored," says Ludacris, that he kills the monotony by hitting local bowling alleys or throwing on the boxing gloves and sparring with his security guard. Not that it's all about finding an adrenaline rush. "Don't get it twisted," says Ludacris. "A massage is good too."
