Jay-Z pulled out what looks to be his phone (because the video is whack) back stage at the American Idol Finale and recorded his wifey Beyonce rehearsing her song "1+1". Check out the video below and see what Jay wrote about his Boo after he posted the video. This is not B's next single, you can expect something new coming this Tuesday!

"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."
