It really isn't that uncommon to see celebrities in drag, whether it's for an acting role or just for plain old fun. From the manliest of men to the most delicate females in pop culture, gender-bending is never really off limits. 

Stars like Bruno Mars, Miley Cyrus, Katy Perry and Adam Lambert have all dressed in drag before, with the first pair donning duds from the opposite sex for 'Saturday Night Live' skits. Perry and Lambert, on the other hand, just love getting their drag king and queen on. The 'Wide Awake' singer has dressed in a wide variety of drag costumes, from Freddy Mercury to cheesy game show hosts, while the 'Better Than I Know Myself' crooner has gotten glam in a dress and heels while out on the town.

Check out these pictures and videos of gender-bending pop stars and let us know which celebrity you thinks looks best dressed in drag!
