LOS ANGELES — Kim Kardashian and Reggie Bush seem to know their way around a photo booth.

Over at the Sundance Film Festival in Utah, the pair apparently posed in the Lifestyles Condom Makeout booth set up at the 5WPR/Butter private party, and from what we were told, the pics were particularly, um, passionate.

“They would be worth a lot,” said the photo-finder the following day.

The Playboy cover girl, reality star and former best pal of Paris Hilton also told Pop Tarts about her favorite Sundance freebie.

“I have been given so many lovely things, which I’m so thankful for — it has just been amazing,” said the surprisingly soft-spoken starlet. “But my favorite? I got some gorgeous underwear.”

However, KK was still “Keeping Up” her signature sensuality at the L-R-G suite when she was spied selecting Luxirie’s super-tight jeans (which had big zippers on the backside to draw attention to that famous booty).

Kardashian rose to fame last year following the release of the sex tape she made with her ex, rapper Ray J. But now that she is the main squeeze of an NFL sensation, is the E! reality queen resurrecting her rep?
