"Alien" doesn't normally bring to mind hotness and sex. But thanks to Hollywood magic, some of our favorite sci-fi characters can also be pretty pleasing to look at. Whether they're trying to save the human race or destroy the planet, they all have one thing in common: looking hot while doing so. In honor of recently released Dead Space 2, where the aliens aren't so easy on the eyes, we bring you the 22 hottest aliens of all time.

22. Sally Solomon in "3rd Rock from the Sun"

Actress: Kristen Johnston

When she asked why she was chosen to be the woman, her commanding officer responded, "Because you lost."

21. Connie in "The Coneheads"

Actress: Laraine Newman

If Chris Farley as a mechanic can pull this alien hottie, then she's clearly open for business.

20. Mary the Three-Boobed Prostitute in "Total Recall"

Actress: Lycia Naff

Three b**bs. Mutant. Prostitute. Done.

19. Martian Call Girl in "Mars Attacks!"

Actress: Lisa Marie Smith

She tried to kill our President but I'll forgive her because of her beautiful disguise.

18. Oola in "Star Wars"

Actress: Femi Taylor

She tried to defy Jabba the Hut and ended up getting eaten by the monster under the trap door. Still, that Twi'lek could dance.

17. Kitty in "Cocoon"

Actress: Tahnee Welch

She was kind enough to introduce humans to the Antarean form of sex, which is a thousand times more org*smic than our boring kind. Wow.
