Paris Hilton arrived in Las Vegas this weekend (March 6, 2009) to celebrate her 28th birthday.  She turned 28 in February, but March 7th she celebrated it at the Hard Rock Hotel & Casino’s Body English Nightclub.   She came with boyfriend, Doug Reinhardt, and 15 of her friends.  They dined at Nobu on Saturday night before making their way to her party.  Paris posed on the pink carpet as fans yelled, “Happy Birthday!” 

Inside Body English, she was presented a cake and her friends sang Happy Birthday to her.  She stayed close to Reinhardt the entire night.
