Christina Aguilera's weight often yo-yos, but the curvy 'Your Body' singer insists that her newly toned figure, which you can marvel at by looking at her so-hot-it-scorches Maxim cover, is not the byproduct of grueling gym sessions. The singer claims that she hardly works out but she does have a foolproof method of keeping in shape.

"If I can squeeze in a workout, great. If not, that's OK, too," the singer said. She is returning to work on Season 5 of 'The Voice,' despite not touring in support of 'Lotus,' which belly flopped. She looks damn fine right now, too.

Instead of hitting the gym to do some cardio or committing to spinning classes, Xtina insists that she keeps in shape by chasing her son Max, 5. "Running around with him all day is pretty good exercise," the singer and coach confessed.

Mom duty is good exercise. We'll give her that much. Looking after a high energy tot is certainly a solid and quality way to burn those pesky calories. Kudos to Xtina for not being tethered to a rigid gym regimen and putting mommy and me time first.
