Pink and Kesha are two pretty bad a-- ladies...  we don't think we'd want to arm wrestle either of them, since they would probably render us useless. But which leading pop songstress would you rather arm wrestle?

Pink has a rock hard body, just take a look at her video for 'Try.' She also has some pretty fierce biceps that would make easy work of any noodle-armed opponent in an arm wrestling match.

Kesha, on the other hand, is a strong-looking lady, but what she lacks in brute strength, she makes up for in wily arm wrestling technique -- something we call: The Crazy Factor. Plus, she rocks a gold tooth. People who rock a gold tooth are NOT to be messed with. Trust us...

So which is it? Vote below.
