You just can’t have it all. Well, at least Ke$ha can’t.

Ke$ha shared the stage at Madison Square Garden in NYC on Thursday with Rihanna for the Last Girl On Earth Tour, and although Ke$ha started the show, Rihanna stole it.

The crowd was having fun as Ke$ha jumped across the stage like a true rockstar, but when RiRi stepped out in a black dress inlaid with lights, her fans hit the wall and went insane!

This isn’t the first time Ke$ha doesn’t get the attention she believes she deserves. Recently she got ignored when stepping out with new Australian boyfriend, Alex Carapetis and wasn’t pleased.
