Christina Aguilera lost three stone in four months since giving birth

Christina Aguilera has revealed she lost three stone in four months since giving birth to her first baby, Max.

The 'Dirrty' singer, 27 -- who gave birth on January 12 -- says she lost weight by doing 90-minute workout sessions five days a week and keeping off white bread.

But her biggest vice? "Oh, my God, candy!" she tells Us Weekly magazine.

"I had a huge craving for candy toward the end of the pregnancy, from Starbursts to Skittles.

"I actually took a picture of myself with my big belly in a little lingerie top, surrounded by bowls of the candy I like.”
