black brings on friday!

When we heard Rebecca Black was going to be part of the America's Got Talent YouTube results show, we couldn't contain our excitement. Anytime we get to see that girl do anything related to a mic and song, we're on it.

black brings on friday!

Oh, Rebecca Black, the YouTube sensation that made us crazy, whether good or bad, with her song Friday. Did you really think America's Got Talent could get away with honoring YouTube sensations and not include Black? It would be national crime.

America's Got Talent ushered four YouTube sensations into the semifinals Wednesday night and Rebecca Black was there to help them celebrate.

The YouTube sensation didn't hit the stage as long as we would have liked, but she did perform an interesting mash-up of Friday and My Moment.

Rebecca Black recently revealed she was bullied out of school, but with a new video for her song My Moment and an appearance on America's Got Talent she's certainly getting the last laugh.

Black also recently appeared in Katy Perry's video for Last Friday Night (T.G.I.F) giving fans a "where's Waldo moment" of excitement. Although, she wasn't really hard to spot -- at all.

Keep cracking on Friday all you want haters, she's bigger than all of us can ever hope to be! Even with her AGT performance being as quick as some would call her career, we still got down!
