Who's Hotter: Ke$ha's Dirty Look At Coachella Or Serena Williams' Bikini Antics?

Define dirrty! So here's a picture of Ke$ha taken from Lacoste L!ve pool party held during the third day of the Coachella Music Fest on Sunday (April 17) in Thermal, Calif.

The "Blow" Singer wears something like a worn out American flag sewn to rag-perfection. 

Why torn? Abraham Lincoln may have used this one after he pooped. Like her music, Ke$ha's outfit is a National Treasure. Ha!

But wait, there's another one!

The uber voluptous Serena Williams flashes her 40-35-60 body. (hmm, okay, i over exaggerated here)

The tennis star is doing some "vacationing"at the beach with some friends on Saturday (April 16) in Miami, Florida. Be proud of what you have girl, flaunt it like there's no tomorrow!

So who's hotter? *Gagging
