2- Ric Okasec
3- Gwen Stefani (great music but what a SKaNK!)
4- Micahel Jackson
6- Marilyn (You spin Me around...blah blah blah)
9-lil'Kim (maybe not so ugly, but what a ho'bag)
10-Tim McGraw (not rock but looks like anorexia)
Mick may be the ugliest mega-star (though not as disturbingly grotesque as Michael Jackson, Jacko is not "Rock"), but the above nominations of Lemmy from Motorhead and especially the guy from the Pogues are the "hands down" winners.
