Robert Pattinson didn't attend the Emmys, but he made a surprise appearance at an A-list afterparty.
But not R.Pattz:
"He was wearing a baseball cap and street clothes hanging at the bar," a guest tells me. "No one even noticed he was there!"
Rob spent most of his night chatting with an older gentleman and managed to avoid the cameras.
Other partygoers were eager to get into more comfortable attire too, and hit up the Havaianas flip flops station, which Jimmy personally requested.
Also in attendance for the star-studded soiree at Trousdale: John Stamos, Adrian Grenier, Andy Samberg, Melissa McCarthy, Julie Bowen and Jon Hamm.
Forget the Governor's Ball! Clearly, Jimmy's fete was the hottest ticket in town. Right, Rob?
