It's been a bit quiet on the Britney front recently, but the born-again party girl was spotted on a steamy night out in New York. According to the American television show Extra, Britney gave revellers at NY nightclub One a shock when she removed her clothes and danced around in her underwear (at least she was wearing underwear!). The Toxic singer and mum-of-two then treated onlookers to a raunchy dance with another woman. Britney's latest exploits have fuelled rumours about her sexuality. Last week, one of Kevin Federline's friends alleged that Britney had sexual liaisons with girlfriends at her Malibu mansion. |
