Of course, you'll have to wait just a little bit longer to see who made the cut for the final 20 (though we're pretty sure that Megan Fox, Jessica Alba, Bar Refaeli et al will pop up), but here's some of the sexy babes who landed in the top 100-21 of Maxim's 2009 Hot 100 list.

Heidi Montag and her fun bags hold the number 81 spot, Amanda Bynes and Ashley Tisdale took the number 74 and 73 spots, while Heidi Klum (62), Audrina Patrdige (57), Kim Kardashian (53), Fergie (45), Charlize Theron (38) and Vanessa Hudgens (27) all made appearances as well. Of course, we're kinda wondering how Lily Allen snagged the number 40 spot over a true beauty like Taylor Swift (number 50), but whatevs!

Do you agree with these selections? And who are your picks for top 20?
