While big brother William is getting ready to take the plunge with Kate Middleton, Prince Harry is living it up as a single and sexy young man.

Princess Diana's youngest boy partied with pals at London's Public Nightclub. With that red hair, and so-what attitude, the 26-year-old hottie is no doubt a chick magnet.

It's no wonder People Magazine named him one of the sexiest men alive. We agree!
