Ashlee Simpson-Wentz has revealed how she lost 50 pounds after giving birth to son Bronx. The 25-year-old singer gave birth to her little boy in November 2008 and said she loved eating what she wanted during her pregnancy.

Ashlee, who is married to Fall Out Boy star Pete Wentz, said to E!: 'I gained 50 pounds, which was awesome! I ate cake and cupcakes. I had a blast!'

Ashlee said one of her weight-loss secrets is a pair of Reebok EasyTone shoes, which claim to tone your bottom and thighs.

She said: 'When I wanted to get back into shape, I worked out and these shoes are amazing because you can really feel them in your booty. But I also worked out and ate healthy.'
