In case you forgot why they call Beyonce Queen King Bey, behold these videos from her weekend performing at the Staples Center in Los Angeles.

Mrs. Carter took her eponymous show to the sold out arena and blew not just fans, but also fellow celebs away with her knockout performances. No one works harder than Beyonce, and it shows!

Katy Perry, who occasionally receives criticism for her live vocals and often awkward dance attempts, was particularly starstruck by the 'Standing On the Sun' singer. Perry took to Twitter to bask in the Bey love -- it's a good thing K.P.'s not the jealous type, lest Beyonce's showmanship made her feel like a plastic bag:

Preach, Katy! To see why she was so in awe, just hit play on any (or preferably all) of these clips. Long live the Queen!
