Robert Pattinson had some intriguing Hollywood nocturnal activity.

The British actor had been sighted with two different women, both older than the actor, as he partied post-Emmy Awards.It was previously reported that Pattinson went around Hollywood with his publicist Stephenie Ritz.

Robert Pattinson and Ritz stopped by the Soho House and later partied with the rest of Hollywood at Trousdale for Jimmy Fallon's post Emmy celebration.

Now, it seems like another cougar rested its paw on Pattinson after reports came in that Kate Gosselin was seen together at a party. Both stars attended Jimmy Fallon's post-Emmy celebration last August 29, and latest reports say the two actually interacted with each other.

HollywoodLife.com quotes a source as saying, "Rob did have a brief discussion with Kate."

"[Robert Pattinson] was sitting with his guy friends, Jimmy and [publicist] Stephanie Ritz, and she came up to chat to him and Jimmy briefly. It was very innocent."

The two had previously met on the set of The View where Robert Pattinson appeared last March and where Gosseling is guest co-host.

But seems like Pattinson was all too loyal to Kristen Stewart who was working in Argentina. He was reportedly in his best behavior.

"He drank beer and played a little pool. He was very low-key - but still one of the last to leave the party," another source said.
