Rumours have suggested that Kristen Stewart and Robert Pattinson may be splitting after the final 'Twilight' DVD is released, but it looks as though Kristen may be pining for her on/off boyfriend, as she was spotted partying with Rob's BFF Marcus Foster at the showbiz couple's fave restaurant.
K-Stew partied with a group, including Rob's pal and reported birthday girl Scout Compton and celebrated at En Sushi in Los Feliz, which is near Kristen and Rob's home, the Mail Online reports.
A source told Perez Hilton: "They were celebrating a friend’s birthday and sang Happy Birthday to her."
Adding, "They all shared the hot chocolate cake."
"Kristen was very nice and sweet. Her friends were also very nice."
According to the source the unassuming sushi restaurant has been a date night spot for Kristen and Rob before.
"Kristen has been here before with Robert Pattinson but he has not been here for quite some time," the source said.

But with Rob thousands of miles away in Australia, the good memories from the restaurant were still not getting Kristen in a better mood it seems, as she was snapped looking rather glum whilst puffing on a cigarette.
Recent reports suggested that although it's previously been thought that the 'On The Road' actress will visit her other half in Aus whilst he's filming 'The Rover', the pair will announce their split once Twi-hards have snapped up the final 'Twilight' DVD.
"Rob & Kristen were asked to not announce a break-up or any relationship trouble until the DVD has been out for a few weeks and everything has sold," a source revealed to Hollywoodlife.
"Since the first couple weeks are the times when the DVD will sell like wildfire. The more DVDs sold, the more money for them. So they are abiding by the request."
