Last week was Beyoncé's birthday, which fell on Labor Day weekend. Since most people were busy,


On Saturday night, the stars were out and about. Bey and Jay-Z were having a party for her 41st birthday at their mansion in Bel Air.

It looks like just about everyone who is someone got an invite,

and when Bey told them to rage, they didn't hesitate to do so. At one point, Jigga himself showed up on camera...

But the birthday girl herself never showed up to be photographed by the press. We've been told that people started coming around 10:30

and stayed until around 3:00. If you look through the gallery, you'll see that it's like a moving belt of famous people.
