Rebecca Black and Katy Perry Perform “Friday” Together On Stage [Video]

Katy Perry and Rebecca Black got together on Friday night to perform the YouTube sensations hit “Friday” to a crowd at a Katy Perry concert in Los Angeles.

When performing to her crowd Perry invited Rebecca on stage and the duo performed the “world’s worst song” together in front of a packed audience who seemed to be enjoying the absurdity of the song.

After the duet performed Black tweeted:

“Thank you SO much @katyperry for having me on stage tonight! What an UNBELIEVABLE experience.(: Definitely won’t forget this one!!.”

If that wasn’t enough of a surprise for the YouTube star, she was honored with the Choice Web Star award during the Teen Choice awards which also occurred last week.

After winning the web choice award Rebecca tweeted:

“Can’t believe I won a TEEN CHOICE AWARD!!!! This is crazy. Thanks to all that voted!”

Rebecca Black also has a new album on the way unfortunately her new song “My Moment” is bad, just not “rise to fame, you can’t take your eyes of this train wreck bad” like was the case with her Friday single.

Here’s the video of Rebecca Black performing with Katy Perry.

It would appear that Katy and Rebecca have struck up quite the friendship, Black even appeared in Perry’s video for her hit single Last Friday Night (T.G.I.F.).
