You know what they say: While the cat's away the mice will play. In the absence of Hollywood party-princess Paris Hilton, Britney has attempted to outdo her in sheer volume of clubs attended and zany antics on Monday night. The club-hop began at Spears' favorite eatery Shu Sushi, traveled to Winston's where Spears' breasts flashed photographers and fans alike. Then moved to Guy's and then to Joseph's after which Britney's fanny shocked onlookers by making a brief appearance. Spears and company closed their night with a trip to Jack in the Box to satisfy the late night munchies.
