Michelle Williams' Sweet Tooth

Destiny's Child star Michelle Williams admits she has one weakness that stands between her and a perfect figure - the 21-year-old is a sucker for chocolate cake.

The sexy singer has to stick to a strict diet to fit into the group's raunchy stage outfits - but she does allow herself one vice.

Michelle says, "I love pastries and other things I should really stay away from. I try to watch my intake every day but it's hard. I also have a weakness for chocolate cake."
