Christina Aguilera has revealed she lost the weight she gained during her pregnancy and gained several bra sizes by breastfeeding.
Aguilera told Us Weekly she has lost the 40lb (18kg) she gained during her pregnancy by breastfeeding her son Max, who was born in January.
She said: "I think they say that when you're breastfeeding, you know, your weight kind of slims down. It's a little easier. It's like a workout within itself. It's very tiring actually and you find yourself snacking more often."
In addition to breastfeeding Aguilera credits 90-minute workout sessions five days a week and staying away from white bread for helping her lose the weight.
Aguilera also says she loves her post-pregnancy chest.
The singer and husband Jordan Bratman have been amazed by the impressive growth in her bust, which has swelled to a massive E-cup, since she gave birth to their son Max in January.
The 27-year-old singer told Us Weekly magazine: "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!"
