Chris Brown has taken a gamble on Las Vegas.
E! News has learned that Brown, who is being investigated by the Los Angeles District Attorney's Office for allegedly beating up his R&B star girlfriend, Rihanna, is holed up at the Hard Rock Hotel and Casino in Vegas. He arrived Wednesday afternoon and is staying in a suite on an upper floor of the hotel.
According to a Sin City source, "They had to kick out any paparazzi that were around and get him tons of security to sneak him in."
"We cannot confirm that Chris is staying with us," a Hard Rock spokesman tells E! News. "However, several of his friends are staying on [the] property."
The reason for the non-confirmation, sources say, is that Brown is under 21 years of age and therefore was unable to check himself into the hotel or keep a room in his own name. Instead, he arrived with friends who reserved the suite on his behalf.
