The actors, who play lovers Bella Swan and Edward Cullen in the hit vampire franchise, had dinner at Gjelina restaurant on Abbot Kinney in Venice Beach before heading together for the opening of a fashion boutique and eyewear store. Owen Wilson, Zach Galifianakis and Olivia Wilde were some of the celebs in attendance, E! Online reported.

"Robert and Kristen were eating next door and peaked in the window after their dinner as the party was wrapping up," a source said.

"Kristen was wearing an old white T-shirt with her hair in a ponytail. Rob was wearing jeans, a tee and a dark coat. It looked like they were on a nice stroll through the neighborhood. They seemed really just into hanging together.

They weren't holding hands, but were really sweet with each other," another eyewitness said.

Pattinson, 23 and Stewart, 19 have refused to comment on the status of their relationship despite mounting evidence to the contrary.
