Backstage in a curtained dressing area labeled "Baby Jane," Christina Aguilera has half an hour until showtime. Though she's still in a terry-cloth robe and a pink hairnet, her mind is on her post-concert plans: playing BrickBreaker on her BlackBerry. "I can't get enough!" says Aguilera, 26, who kicked off her 41-city North American tour last month. "It's a nice unwind. My adrenaline is pretty crazy after a show." After a roughly 90-minute set with 10 costume changes, it's no wonder. "It helps being in a great place in my life," she says, referring to her "support system and backbone," music exec Jordan Bratman, 29, whom Aguilera wed in '05.

While "Jordy" rarely goes a week without joining his wife and three dogs on the road, he gave her an antique locket with their wedding photos to keep with her at all times. Other tour must-haves? Diptyque candles, hot tea and lots of movies. "I love my DVDs," says Aguilera, who pops in anything from The Sound of Music to Halloween. "They're my comfort away from home."
