Thanks to a well-balanced diet, yoga, and regular workouts with her trainer, Tee Sorge, Christina Aguilera reportedly lost almost 50 pounds in 2013 and has never looked better. But don’t expect to see her in the gym too much; the pop diva says her son Max gives her plenty of exercise:
“If I have to choose between working out and spending time with my son after a hard day, it’s not even a question,” she’s said.
