Amy Winehouse and Lady GaGa
Paris Hilton, Nicole Riche, Cher, Whitney Houston, the Kardashian things, I guess pretty much any of the "slores" from E!, and a few others I can't think of at the moment would top this list as well.

A little off topic, but on the other side...
Emma Watson, JoJo, Amanda Michalka, Emily Osment, Jennette McCurdy, Janet Jackson, Katy Perry, Miley Cyrus, Nicole Scherzinger, Hayley Williams, Taylor Swift, and Vanessa Carlton would be near the top of celebrities I would date.
