Pop star Britney Spears is celebrating being single again by getting a new tattoo of a small star on her right hand. The TOXIC star, 25, recently apologised to fans for her hard-partying ways, but has not cut down on her nights out on the town. The star and a group of friends, including her 15-year-old sister JAMIE LYNN, hit the Devil Doll Tattoo + Body Piercing in Studio City, California on Tuesday (19DEC06). The singer, who has two young sons, Sean Preston and JAYDEN JAMES, was seen sporting disheveled hair and constantly adjusting her wayward bra strap while she was getting the new tattoo. According to website, TMZ.com, Spears was followed by a pack of paparazzi and set off a media frenzy at the tattoo parlour.
