Guests arriving at the Ritz-Carlton Istanbul this weekend were surprised to find rappers 50 Cent, Ne-Yo, Akon and SkyBlu of LMFAO and their entourages already in place. The artists were there for the Velvet Villains Vestival, which on Friday and Saturday night drew fans from across Turkey and the Middle East to KucukCiftlik Park, where they jammed till 2 a.m. One female fan who was brought back to the hotel by Ne-Yo was left sitting in the lobby for hours. She begged the front desk to let her have a key to his suite, which they refused to do. On Saturday afternoon, groupies descended on the rooftop pool hoping to catch a glimpse of the rappers, who didn’t appear until later.
