X17 XCLUSIVE - Jessica Simpson Hides In Her Range Rover After Leaving Plastic Surgery Office

Hmm, why would she do something like that?

Yesterday afternoon we spotted Joe Simpson driving out of a Beverly Hills medical building, and our X17 photographers on the scene tell us Jessica Simpson was cowering in the back seat of the SUV as her two friends successfully shielded her from the cameras.

Jessica and her entourage were snapped visiting two different doctor's offices with numerous plastic surgeons, and get this -- they spent a total of nearly 6 hours inside! Jessica was in the first building for 3 hours, and she stayed at the second one for two and a half hours before emerging.

Doesn't seem like she was just getting a cortisone shot on a zit or getting her teeth whitened, does it? Jess has admitted in the past to getting lip injections, but in a 2008 interview she said she regretted the Restylane because she looked like "a blowfish," and she hinted that she wasn't going to do it again. Hmm, was she being 100% honest? Or is she getting something else done? I guess we'll find out soon enough!
