If our mother was doing this we'd be mortified, but we have to admit she looks damn good!

Lisa Rinna is braving the cold winter temperatures by, well... taking off her clothes! The Real Housewives of Beverly Hills star stripped down to her bra and undies to show off her insanely sculpted physique on Instagram the other day, and we seriously can't believe she's 53-years-old! Husband Harry Hamlin is one lucky dude.

The reality star has been the subject of plastic surgery rumors for years, but she claims other than her lips and a boob job, she's au naturel. "No I don't (have new boobs), but I have boob pads in. It's all an illusion people, I can do many things with this body," she confessed during a recent appearance on Watch What Happens Live!.

Her co-stars have accused her of never eating and being too skinny, but we think she looks fit and toned based on this picture!
