What better way to ring in the New Year than with a Grammy nominated singer like
Katy Perry? Perry headlined the 'Gridlock' New Years Eve party at Paramount Studios in Los Angeles, which brought in celebs and party goers alike.
The "Hot N Cold" singer, who was sporting a mini dress and new bangs, performed at midnight to a packed house.
LMFAO took over after Katy and gave party goers just what they needed--a rockin good time!
Hollyscoop was at Paramount for the big party where we caught up with the celebs on the red carpet right before the party got started. Check out our special New Years Eve coverage below...
