Christina Aguilera’s feet increased by two sizes when she was pregnant.

The 27-year-old singer – who gave birth to Max Liron, her first child with husband Jordan Bratman, in January – admits she was stunned by the amount her petite feet ballooned in size.

She said: “My stomach was really where I carried my weight. Toward the end of my pregnancy, I felt really big – I gained about 40lbs, which is a lot for my size. My hips also changed significantly. And my feet grew from a size five-and-a-half to a size seven in flats!”

Christina also revealed she was thrilled when she returned to her regular size, because she could start wearing her old clothes and shoes again.

She said: “Thank God my feet went back to normal. I would have been so depressed if I had to get rid of my shoe collection!”
