Making for quite the memorable night, Kristen Stewart rang in her 21st birthday with a big bash at Executive Suites Hotel's Rockwell's Bar & Grill in Squamish, Canada over the weekend (April 9). With the first photos documenting the grand occasion just being released, the Bella Swan babe can be seen being doted with her motorcycle present from boyfriend Robert Pattinson in an oh-so-sweet moment. A short while later, fellow "Twilight" castmate Taylor Lautner was spotted giving girlfriend Lily Collins a lesson on how to ride the cycle as he hovered over her while she sat down on the motor. Meanwhile, Rob and Kristen were also spied sharing a quick kiss before mingling with the rest of the cast and crew as the party finally started to wind down around 1am. Of the scene, a source told Us magazine, "Rob and Kristin were together all night. They held hands and he kissed her cheek a bunch of times." Enjoy the pictures of the scene from Kristen Stewart's b-day bash/cast wrap party in Squamish (April 9).
