You’ll probably recognize a couple Gleeks in Katy Perry‘s new celeb-filled music video for her song “Friday Night.” At the beginning you’ll see Darren Criss as Aaron Christopherson, and throughout the video Kevin McHale plays the adorkable Everett McDonald. Check out Kevin in character in a hilarious promo for the music video:

Other celeb cameos include Rebecca Black, Hanson, Kenny G, Corey Feldman, and Debbie Gibson. So what do you think?

In addition to Glee being nominated for a whopping 13 Teen Choice Awards, Cory Montieth, Mark Salling, Chris Colfer, and Kevin McHale have been invited to co-host the award show itself! They’ll be chilling onstage next to Katy Perry, who is also co-hosting the event.

Also on the itinerary are Eclipse stars Taylor Lautner, Robert Pattinson, Ashley Greene, as well as Zac Efron, Jane Lynch, Leighton Meester, Channing Tatum, Zachary Levi, Ellen DeGeneres, Sandra Bullock, Jim Parsons, Miranda Cosgrove, and Kristin Bell, to name a few. There will be performances from Jason Derulo, Katy Perry, and Travis McCoy. The TCAs will air on Monday, August 9 at 8:00-10:00 PM ET/PT on FOX.
