Katy Perry, Darren Criss & Rebecca Black Highlight “Last Friday Night” Making-Of

Katy Perry’s “E.T.” and “Firework” may have been the big winners at the MTV Video Music Awards on Sunday, but that hasn’t stopped the pink-haired songstress from showing some love to her latest clip, “Last Friday Night (T.G.I.F.).” A behind-the-scenes video, which features interviews with the party epic’s stars (such as Rebecca Black, Darren Criss, Kevin McHale, Debbie Gibson, Corey Feldman and, yes, Kenny G) was thrown online to celebrate the one-year anniversary of Teenage Dream’s release.

“I must say, I think this video might go down in the record books for the most money spent on streamers and toilet paper,” youngest Hanson brother Zac declares on the set.

Meanwhile, Debbie Gibson complains, “Where’s Corey? He’s been in hair longer than me, for god’s sakes! It’s always the boys — they’re so precious.”
