GossipCop on Rob and Kristen's Alleged 'Pre-Oscar Dance Party'

This is in response to the earlier posted rumor about Rob and Kristen attending a Pre-Oscar bash in Hollywood.

GossipCop Robert Pattinson and Kristen Stewart attract attention wherever they go, so their rumored joint appearance at a pre-Oscars Chateau Marmont bash last Friday would have been news no matter what.

But Us Weekly raises the ante, claiming the Twilighttwosome “threw their hands in the air like they just didn’t care,” spending all night on the dance floor, where one “fellow reveler” says “they definitely kissed a few times.”

According to the magazine’s source, the highlight for the couple came when DJ Jesse Marco played Jay-Z andAlicia Keys‘ “Empire State of Mind” (“They went nuts for [it]!”)

That sounds pretty cool and all – but did it actually happen?

Gossip Cop received many questions about Pattinson and Stewart’s supposed attendance at the soiree, and while it’s possible the duo danced the night away, no one has been able to confirm that they were there.

The event’s own photographer tells Gossip Cop he did not see Pattinson and Stewart at the party, and one of the organizers tells Gossip Cop, “They were not on the list [of expected celebrities].”

Again, it’s possible that Pattinson and Stewart were among the crowd that included stars likeHalle Berry, Ryan Gosling, Miley Cyrus and Natalie Portman.

But the absence of any corroborating eyewitness accounts at this point, in addition to what our sources tell us, make Gossip Cop skeptical that the Breaking Dawn stars kissed on the Chateau Marmont dance floor last week.
