Christina Aguilera: 'I can't diet'

Christina Aguilera has revealed that she finds it hard to stick to a diet.

According to The Sun, the popstar has been trying to get back into shape after giving birth 19 months ago.

She reportedly exercises for an hour every night after putting her son Max to bed.

Aguilera said: "I don't diet because I can't. 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."
