Leighton Meester may look a bit like Alicia Silverstone, but after watching her strut her stuff in an itsy-bitsy bikini in a skintacular guest appearance on the Fox hit North Shore, all comparisons are off. That's because you'd be clueless not to see this young thing as a hottie in her own right. She began her career innocently enough with a recurring role on 7th Heaven and developed as both an actress and a piece of ass on various boob-tube shows, such as Crossing Jordan, Family Affair, and Boston Public. And she's even been a bit of a swinger, playing Jane's sister on Tarzan. While this sweet young thing has yet to show off her sweet young things, she gets pretty close, sunbathing topless on North Shore. Her big-screen résumé has yet to produce any skin, but with with her popularity (and fans' laps) on the rise due to her bad girl role as Blair on Gossip Girl, it's only a matter of time before we see Meester's keester.
