Robert Pattinson Parties Without Kristen Exclusive

Robert Pattinson Parties Without Kristen Stewart On Eve Of Her 21st Birthday! Exclusive

Rob and Kristen were nowhere to be seen on her actual birthday — but Rob managed to squeeze in some 'Breaking Dawn' boys time at a sports bar the night before!

Robert Pattinson must have let Kristen Stewart get her beauty sleep, because she definitely wasn't with him the night before her 21st birthday! An insider tells HollywoodLife.com the 24-year-old actor was spotted with his Breaking Dawn co-star Peter Facinelli on April 8 at Grizzly Bar & Grill, one of his favorite hangouts in Squamish, BC Canada.

Rob and Peter were having a "casual night" at the low-key bar near their hotel the Executive Suites.

Maybe the boys needed a chill night before Kristen hit the big 2-1 the following day! We had a huge scoop that the entire Breaking Dawn cast threw a party on Kristen's birthday. We were on the scene and the hotel was closed off to the public starting at 7pm and was guarded by the Royal Canadian Mounted Police all night. We were inside the Twi-bash but there was no sign of Robsten — sigh.

But we can tell you one thing: those werewolves and vampires know how to throw a party
