Ke$ha's 2011 Billboard Awards Performance

She’s always up for a good time, and earlier tonight (May 22) Ke$ha was spotted at the 2011 Billboard Music Awards.

The “Your Love Is My Drug” songstress took the stage at the MGM Grand Garden Arena looking absolutely fabulous as she entertained the crowd a rendition of “Animal” and her current single “Blow”.

Earlier this week, Ke$ha started rumors that she was digging on T-Pain by tweeting playful messages back and forth with him.

At one point, T-Pain shared a picture of them nuzzling, with the caption, "Ladies and gentlemen I've upgraded from loyal stalker. Get ready for K-Pain."
