Britney Spears joined husband KEVIN FEDERLINE in Las Vegas, Nevada this weekend (ends30JUL06), where the aspiring rapper had been shooting the music video for his debut single LOSE CONTROL. The couple, along with their 10-month-old son Sean Preston, hit the town on Thursday night (27JUL06), along with seven friends and dined at Tao at the Venetian. On Saturday (29JUL06), Federline filmed the video for his new song at Pure Nightclub at Caesars Palace and wrapped around 10:30pm, when the club then opened to the public. Federline and his crew stayed to celebrate and Spears, who is expecting the couple's second child this autumn (06), stopped by shortly after midnight. After spending half an hour with her husband, the TOXIC singer then headed back to Tao with a few girlfriends and watched the action on the dance floor. Federline remained at Pure where he took centre stage, emceeing from the DJ booth and playing his song four times to get the crowd going.
