Reality sisters Kim Kardashian and Khloe Kardashian Odom spent a little family time together yesterday promoting the diet supplement QuickTrim at a CVS Pharmacy in Sherman Oaks, Ca. The girls are spokespeople for the brand and spent the day signing autographs, posing for pictures and chatting with fans.

Proving that they are more than just the pretty faces--and bodies--featured in commercials for the supplement, the sisters each took a turn swallowing a dose of the product as fans and photographers looked on. Always ready for a great photo-op, at one point Kim even grabbed a bottle of the supplement and pretended to pour it down Khloe's throat amid a flicker of flashbulbs.
