When they had a break from filming (him New Moon and her Beezus and Ramona), Lautner, 17, picked up Gomez, 16, at her hotel Saturday, and the young couple headed for dinner at the upscale Cactus Club in the town of Coquitlam.
After dinner, they linked arms and walked to a nearby cineplex to see the Beyonce Knowles thriller Obsessed. "They were cuddling throughout the movie and sat very close together," says an onlooker. "[They were] definitely acting like they were boyfriend and girlfriend."
It's not the first time the couple has been spotted together. They recently grabbed dinner with some friends – including Lautner's Twilight costar Robert Pattinson. They were also spotted drinking lattes together at a nearby cafe on Thursday. "They were just sort of doing their own thing, talking," an onlooker tells PEOPLE.
Despite the cuddling at Saturday's movie, sources say it's not exactly a romance. "He has been visiting her on the set and they've been hanging out [in Vancouver]," says a source. "The two of them are friends."
