Weight watcher Christina Aguilera

Christina Aguilera is determined to lose her baby weight.

The 'Dirrty' singer - who gave birth to son Max, her first child with husband Jordan Bratman, in January - admits she is finding it tough to shift her last few post-pregnancy pounds.

She said: "Now I am back in the gym trying to eat as healthy as I can except for my one cheat day a week."

However, Christina, 27, confesses the lack of calorific treats is making her mad because she loves food so much.

She added: "I hate deprivation. I just can't do it. If I feel deprived I get really angry. I don't do the no-carbs thing. I have to have my carbs. No cheating for me means no real junk food."

Christina previously admitted she loved the effect pregnancy had on her breasts.

The 'Ain't No Other Man' singer's bust swelled to a massive E-cup leaving husband Jordan with a massive smile on his face.

Christina said at the time: "It's kind of hilarious! I've never fit into an E-cup before. I look at my husband and go, 'Guess what size this bra is?' And when I tell him, he's just amazed. We have kept the tags that prove it, to look back for memory's sake!"
