Kristen Stewart celebrated her 21st birthday in style over the weekend by partying with Robert Pattinson at a restaurant in Vancouver, Canada.
The rumored couple is in the city filming scenes for the latest installment in the Twilight franchise along with the rest of the cast, including Taylor Lautner and Ashley Greene.
Stewart reached the milestone on Saturday and invited her castmates to the Rockwell's Bar & Grill in Squamish, where they ate oysters and partied into the night, reports UsMagazine.com.
The actress was reportedly handed a chocolate birthday cake, while Pattinson led the crowd in singing Happy Birthday to the star.
A source tells the publication, "Rob led the crowd singing for her, and you could tell she was so embarrassed but in a cute way! Everyone was in a good mood, but it was a bittersweet night (as filming is almost complete)."
