Kim Kardashian celebrates Rob Kardashian Birthday

It must suck being Khloe Kardashian at times. At Rob Kardashian’s 24th birthday celebration at the Jey Nightclub ay the Mirage Hotel & Casino, Khloe was looking super hot and all smiles. Then Kim Kardashian walked out in a dress that immediately grabbed everyone’s attention – a very sexy dress by designer Hervé Léger.

Cleavage was exposed to the max, and guys in the place couldn’t seem to avery their eyes from Kim while the still hot sister Khloe sat in the background. She must be used to it by now though we would say.

Also in attendance was boxer Floyd Mayweather, helping Rob eat some of his huge birthday cake and have a few drinks with friends and fans.
