Kim Kardashian was joined by her boyfriend Reggie Bush in celebrating her 28th birthday at LAX at the Luxor Las Vegas. Kim was looking stunning and curvy in all the right places in her full length green dress. Her sisters, Kourtney and Khloe, were also looking very sexy and tad slutty if you want to know the truth. Kourtney was showing off the cleavage while Kourtney was working a super tight low cut black number and didn’t leave much to the imagination. Reggie must be feeling OK with his knee surgery to be heading out in Vegas while his Chargers battle the Saints in London.
