You might've noticed a bit of awkwardness between Kim and Kyle Richards during Bravo's Watch What Happens Live, after The Real Housewives of Beverly Hills premiere.

It's not an act. Paris Hilton's aunts — sisters of Kathy Hilton — already have a natural tension and the show just exacerbates the conflict. "We're very different and we clash sometimes," younger sister Kyle told People at the show's premiere. "Being in front of the cameras brings out things that you don't really expect." What's the state of their relationship now? "It's awkward," Kyle said, adding that all the drama is real. "There are no lines; there's no script. It is what it is." As Kim said later in New York, "Things are said and done that you just can't take back."

The sisters do have some of their best times together on the show, Kim says, but also the "worst conflict ever... I 've learned a lot from this season." As Kyle sums it up, "It's been very straining on our relationship — without a doubt."
