Robin Thicke and T.I. closed 'The Grammy Nominations Concert Live!!' tonight (Dec. 6) in Los Angeles with some fancy footwork and some help from Earth, Wind & Fire as they performed 'Blurred Lines.'

While their partner Pharrell Williams was absent from this soulful, funky and fun version of the biggest hit of the summer, Thicke and Tip did fine without him on their newly-nominated jam.

Dressed in suits, with Thicke's tie undone and T.I. rocking teal while showing off some seriously impressive dance moves, 'Blurred Lines' came to life in a big, bold and unforgettable way.

Congrats to Thick, Tip and Williams on their nominations. The 2014 Grammy Awards air on Sunday, Jan. 26.
