Kristin Cavallari and Paris Hilton Enjoy Bikini Time in Vegas

The bikinis were out in Las Vegas this weekend as Kristin Cavallari hosted a party at Liquid Pool at CityCenter on Saturday and Paris Hilton hosted Rehab Pool Party at Hard Rock Hotel Casino on Sunday. Paris was tweeting up a storm poolside and continued to wear her love of pink in her hot pink bikini while her sister Nicky kept covered up. Kristin opted for a black bikini and matching cover up and also tweeted from Vegas, as well as talking about Heidi Montag's new surgically altered body, which she displayed in Vegas earlier this month.
