Here's a fun pic of Glee's Darren Criss and Kevin McHale on the set of the music video for Katy Perry's new single Last Friday Night. The video was filmed last month in Los Angeles (check out a pic of Katy on set here).
Hanson also appears in the video as the house band. Taylor Hanson told MTV News that he was thrilled to get the invite:
"We were flattered to be asked, and it was great to be a part of it. We had a really good time. It was one of those things that worked out really well. They said [they] needed a band to play the party, and we thought we could bring the party — even if it was a fictional party.
There's a ton of other cameos in Katy's video. See how many you can spot:
