Lauren Conrad poses topless for magazine

Lauren Conrad has stripped off to pose topless for a new magazine cover.

The former The Hills star wears nothing but a pair of white bikini bottoms in a poolside shoot for Glamour's May (12) issue.

Conrad insists she is normally reserved when it comes to showing off her body - and admits a recent vacation to Mexico was the first time she has donned a swimsuit in public in years.

She tells the publication, "On the vacation to Cabo (San Lucas), I wore a bathing suit on the beach for the first time in years. Usually I'm just petrified.

"A couple of years ago someone zoomed in on my cellulite and it was so mean. I took it really personally. I haven't worn a bathing suit in L.A. in years because of that."
