Christina Aguilera "I Don't Diet"

Christina Aguilera has admitted that she finds it impossible to diet, so keeps in shape purely through exercise.

The beautiful blonde, who gave birth to son Max 19 months ago, has revealed that she loves food so much - that rather than cut down on what she eats, she fits in a tough work out every night to burn off the excess calories.

"I don't diet because I can't," The Sun quotes her as saying. "I love my food too much. I can't even cut down on carbs because that's so hard for me."

"So I eat what I like and make sure I work out for an hour when Max goes to bed. It's hard but it works for me."
