No this isn't a late April Fool's joke. People Magazine featured Rob & Kristen in their "Caught in the Act" feature on Wednesday:
• Looks like the Twilight cast has a favorite new restaurant! In Vancouver to shoot New Moon, Robert Pattinson, Kristen Stewart, Taylor Lautner and others grabbed dinner at India Bistro – and were soon recognized by fans, who approached for photos after the group finished their meal. Owner Kamal Mroke tells us the group was "very nice" and says they returned for lunch the next day. After their dinner of Palak Paneer and Chicken Jalfrezi, the cast left in two cabs – Pattinson in his own, while the others jumped in another. According to Mroke, the Twilight stars have been in for a meal every week.
Thanks for the info Emily!
