The duo, along with singer Marcus Foster, went unnoticed by fans. They walked towards the curtained-off area on stage, where they watched Marcus. After the show, RoPa and Kristen went out stealthily to avoid the fans and got into a waiting cab.
"Kristen and Rob, just the two of them, came in and walked towards the curtained-off area on stage where they watched Marcus. They seemed to go unnoticed," People.com quoted a source saying.
Later Rob and Kristen showed up together with a group of friends at the Chateau Marmont, where they hung out and appear to have spent the night. They were photographed the following morning separately stepping out onto one of the hotel room balconies.
However, it is said that Kristen Stewart has recently split from her boyfriend and left a clear path for Pattinson to try his luck. Robsten will soon fly off to Vancouver to begin filming third Twilight movie Eclipse, which is set to start later this month in Canada.
