Kim Kardashian and Reggie Bush: Not Engaged... Yet

Like the ejaculation periods of many men who watch Kim Kardashian nude in her sex tape, talk of this socialite and Reggie Bush getting engaged is premature.

"It's not true," Kim told Us Weekly of the rumors that heated up following this couple's intimate partying on New Year's Eve. "Not yet!"

It certainly sounds as though Kardashian and Bush might follow the recent, matrimonial lead of Katherine Heigl and Josh Kelley, doesn't it?

But which couple will last longer: Kim and Reggie, or Britney Spears and Adnan Ghalib?
