Paris Hilton and LMFAO's RedFoo were looking perfectly chummy in matching sunglasses at Sundance this past weekend -- likely the result of spending more than a little time together.

P-Hilz and the 'Party Rock' singer hung out behind the sound booth with DJ Kascade (not pictured) at the T-Mobile Presents Google Music at TAO event and spent most of the evening throwing up 'rock on' hand signs, when they weren't performing. Yes, performing.

Like we told you last week, Paris is toes deep in a new album, the follow-up to her stand-alone 2006 single, 'Stars are Blind.' And who better to help her than a duo with top notch party pumping experience? When a nightlife-loving hotel heiress meets a couple of crazy -- and crazy successful -- music dudes, well, we're in for a good time.

As demonstrated by the photo above, Paris and RedFoo are comfortable at each other's sides, and Paris even sported some uber fuzzy earmuffs at the film fest to match her newfound friend's huge mop of curls. As for the LMFAO spokesperson, he rocked out with his song out, wearing a neon pink tank with the words to his own 'Champagne Showers' song scribbled across the front.

This looks like the beginning of something great, no?
