Have The Hiltons Found Happiness?

It's such a relief to see Paris Hilton smiling and laughing again - after all, it wasn't too long ago that we saw her crying her eyes out in the back of a cop car! Last night, however, Paris was flashing her pearly whites everywhere she turned up - at the Terrace Room, at home, at the SkyBar - and her ebulliance was so infectious that even the typically-stone-faced Nicky couldn't help but smile along! (Of course, we'd be smiling too if we scored invitations to LeBron James' ESPN Awards afterparty - especially if we got to stay until the wee hours of the morning!)
