Kim Kardashian and boyfriend Reggie Bush steamed up a makeshift photo booth hosted by Lifestyles Condoms while in Sundance last week.

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.

Word on the street is that Kim and Reggie are secretly engaged.  Kim rose to fame when her sex tape with rapper Ray J. was released online.  She was previously married to record producer Damon Thomas.
