Just found this today and thought to share with all. Kristen and Rob were caught together at a private party and dinner with other cast mates. Here is the article that I found on People.com

• Robert Pattinson and Kristen Stewart, hanging out at a private party at Players Chophouse, a restaurant in Vancouver. "Rob and Kristen stayed pretty close together throughout the night, often going outside to chat with other guests they seemed to know," a source tells us. The couple mingled with Twilight costars like Kellan Lutz and Ashley Greene and checked out the night's musical entertainment courtesy of costar Jackson Rathbone's band 100 Monkeys. A few days later, Pattinson and Stewart grabbed dinner with friends at Cin Cin restaurant. "Rob and Kristen were seated beside each other and very close all night," said an onlooker.
