Kim Kardashian says there's been no smooching between her and Terrence Howard.

I believe Kim. Usually when she's with someone, there's a lot of cameramen around. :)
US:
Despite a Page Six report that reality star Kim Kardashian was spotted "making out" with Terrence Howard, Kardashian tells Usmagazine.com that they are mistaken.
"They must have me mixed up with his new girlfriend, Miss USA Rachel Smith!" Kardashian tells Us. "I was never at the places they said... I've met [Howard] a few times but we're not even friends."
We knew something was fishy -- Kardashian doesn't look a thing like Terrence Howard's type: himself.
