Beyonce's Video Shoot
Queen B films her latest video.
If her mind-boggling Billboard Awards performance, her slew of hit singles or her American Idol performance haven’t convinced you that Beyonce is one of the most talented performers around, well then get ready to be convinced.

Her beau Jay-Z posted a video from her Idol rehearsals which he titled “Pregame.” As Beyonce and her crew sit behind the scenes in a waiting room, Beyonce begins belting out her new tune “1+1″ while standing in front of the mirror. Taken with what seems to be a simple cell phone camera, B’s voice rings through the air pitch-perfect and as if she was singing into a PA system. Only she wasn’t: She was 100% unplugged, and still sounded absolutely flawless.

Jay posted the following on his site to accompany the video: “Sometimes you need perspective. You’ve been right in front of greatness so often that you need to step back and see it again for the first time. This is the dressing room rehearsal for American Idol. NO MICROPHONE. No effects.”

It’s been a wild week for Beyonce and her performances. On Sunday she gave one of the most dazzling awards show performances in recent memory on the Billboard Awards, complete with a digital background that was choreographed to her routine. Watch it below:
