The second performance of the night went to Robin Thicke and his No. 1 Billboard song 'Blurred Lines.'

Pharrell came out to join Thicke as they brought out a live band for 2013's summer anthem so far.

Thicke and Pharrell went all through the crowd singing to the ladies, with beaming smiles. T.I. joined the crooning duo once they returned to the stage to close out their set.
