Robin Thicke's song 'Blurred Lines' is on top of the Hot 100 this week and for good reason, that shiz is catchy! It's funky and bouncing beat appeals to pretty much everyone, including Miley Cyrus

Robin and his collaborator on the song, Pharrell were on hand at the Myspace re-launch party on Wednesday night to perform their hit track. Since Pharrell and Miley are pretty much BFFs now, the super-producer decided to bring out his buddy for a little help performing the track.

Miley let Robin and Pharrell have the spotlight for just long enough before she came out dancing on the stage hand-in-hand with Williams. The 'We Can't Stop' songstress sung a couple of 'Uh-huhs' into the mic before resorting to some serious dancing in her pajama jeans. The songstress tweeted her praises for Pharrell (but not Robin Thicke for some werid reason) after the show.

Downside was... there was no twerking! She must have gotten that out of her system at the Juicy J concert over the weekend.
