Lauren Conrad keeps her clothes on, Ashley Tisdale takes them off for Allure

Lauren Conrad has the cover of Allure's May issue, but she's staying fully clothed thank-you-very-much.

Ashley Tisdale, Keri Hilson, Kaley Cuoco and more are baring it all for the mag, but Conrad is holding her own with a gorgeous set of pictures that keep the skin showing to a minimum. To see Tisdale in all her glory, go ahead and click here.

"I'm not a sexy person. I'm OK with it," Conrad says. "I've never been the sexy girl. Whenever I've had a boyfriend, he's always been like, 'Oh, you're cute.'"

We don't know who she's been dating -- OK, that's a lie -- but we can think of more than a few guys who would beg to differ. The "LA Candy" author has been linked to Brody Jenner and Jason Wahler in the past, but is currently attached to actor Kyle Howard.
