See Fergie's Surprise Clippers Flash Mob Performance -- and Clippers Owner Steve Ballmer's Awkward Dance

Fergie pulled off a surprise flash mob performance on Wednesday, treating fans to an unexpected concert!
Following the Clippers’ victory against The Lakers at the Staples Center, Fergie stepped out of her seat and began performing her hit “L.A. Love” and many people throughout the stadium joined in from the ushers, camera operators and even a guy selling popcorn. 
Even Steve Ballmer, the new owner of the Clippers, got in on the action with some very, uh, awkward dance moves.
Check out the video above to see how it all went down.
