Rihanna Steals Ke$ha's Thunder At Madison Square Garden

You just can't have it all! Or maybe Ke$ha can't. She shared the stage at Madison Square Garden in NYC on Thursday with Rihanna for the Last Girl On Earth Tour, and although Ke$ha started the show, Rihanna stole it. The crowd was wild for Ke$ha's rockstar performance, but when RiRi stepped out in a black dress inlaid with lights, her fans hit the wall and went insane!

Both artists have a niche for fun, vibrant dance music that can get any crowd pumped, but clearly Rihanna is the more experienced one. Ke$ha did go all out for the show, but her stage looked more like a scene out of Chuckie's Bride.

After belting out 'Russian Roulette', Rihanna ran right into a crowd pleaser, "Hard," and did a quick wardrobe change into a peachy pink and glittery body suit. She even rode on her own hot pink military tank on stage with a mickey mouse ears helmet on. Ke$ha's garbage and trash fashion paired with Rihanna's smoking hot wardrobe changes really made last night's show one for the books. These girls aren't your typical pop stars!
