After having gone out with sister Kim and Kim's boyfriend Kanye West, Khloe Kardashian isn't as convinced as the rest of the world is that their relationship is really that serious just yet.  She did acknowledge that the two have been good friends for years and because of this, their relationship has a great possibility to develop into something special over time since they are already so comfortable together.

This is what Khloe told Andy Cohen, on "Watch What Happens Live":

"We had a double, triple, foursome date, whatever. I don't think it's serious. I think it's too soon. But, because they're friends for so long, it's just so easy, and that's something I love seeing about Kim."
