Lauren Conrad Looks At Various 'Real Housewives' Beauty Fads On 'Watch What Happens: Live' (VIDEO)

Lauren Conrad became a household name on the MTV reality series "The Hills." She has since written several books, launched a beauty website and even has two fashion lines. So who better to critique some of the new beauty fads the castmembers of the various "Real Housewives" series have gotten into on "Watch What Happens: Live."

What made the segment even more fun was that Conrad recognized several of the techniques as things she had tried herself. One shot of Kim Zolciak wrapped up like a mummy was described by host Andy Cohen as "LA Slimwrap mummy wrapping."

"I do this! It's awesome!" Conrad said excitedly, adding, "You can lose like 3 pounds."

Ramona Singer's bio-scuplting? Conrad's done that, too. While fans were loving her appearance on Twitter, though, don't expect to see Conrad on a "Real Housewives" show or on any other show for that matter. She's committed herself fully to her writing and fashion endeavors.

Tune in to "Watch What Happens: Live" every Sunday through Thursday at 11 p.m. ET on Bravo.
