Kim Kardashian: In Love, In the Navy

Kim Kardashian performed with The Pussycat Dolls Friday night in Las Vegas.

But the topic of conversation was whether or not this sex tape star's own dirty-word-for-vagina would be reserved for Reggie Bush for the rest of her life.

"I think I finally made the right choice. He's just a really sweet, normal guy," Kardashian said of her football-playing beau, telling People Magazine that the couple talks about marriage.

The running back wasn't with Kim when she performed with the the scantily-clad singing group inside Pure Nightclub, but she did text him a preview of that evening's outfit (pictured above and below).

"I did iChat him and I had my costume on for his approval," she said. "I did my whole dance for him when I was practicing last night. He thought it was so cute."
