LATEST: Just days after impulsively shaving off all her hair at a California salon, Britney Spears hit the Hollywood club scene again. The pop star arrived at The Roxy in West Hollywood, in a platinum blonde wig and sunglasses at 11pm on Sunday night (18FEB07). The 25-year-old went into the club's VIP bar, On the Rox, where she went unrecognised. According to American publication People, Spears and her friends "sat by themselves". A source explains, "No one noticed her, so much so that no one ever went over to her and offered her a drink or anything. "She was wearing sunglasses for at least part of the time she was inside, which might have been why." A private birthday party for 80 people was taking place in the VIP section, which included karaoke. The TOXIC singer stayed for an hour and a half and left when a partygoer started singing karaoke to her song BABY ONE MORE TIME. Spears reportedly left around 1am with a brunette friend and drove to the posh Beverly Hills Hotel followed by a pack of paparazzi.
