Kim Kardashian and beau Kris Humphries are clearly a couple in love, and Khloe Kardashian says her big sis is pretty set on becoming Mrs. Kim Humphries.

"She thinks she is," Khloe told E! about the potential nuptials. "But Kim is a hopeless romantic. That's just Kim."

"She likes having her boyfriends," Khlo continued, “and you know, when it dies out, I think it's fun to have the new phase, and I think Kim likes that."

But Kim must really have marriage on her mind, because Khloe says she borrows her massive 10-karat engagement ring frequently.

"She takes pictures with it. I'm like oh my god, you've got to give it back," Khlo revealed.

Kim even tweeted about her “future husband” this weekend. “I am so happy my future husband just surprised me!” the celebutante wrote. Sounds like someone’s getting pretty serious about tying the knot!
