Katy Perry-“Last Friday Night” Video Teaser [VIDEO]

Katy Perry has created a geeky teen alter ego named Kathy Beth Terry to promote the video for her song "Last Friday Night (T.G.I.F.)". She already has her own Facebook and Twitter accounts. According to her Twitter profile, Kathy says she's, quote, "13 and in the 8th grade.  I like Sudoku puzzles, the solar system, high-school science fairs, Skip-It, Weenie Babies and LOVE JTT!" (JTT by the way is Jonathan Taylor Thomas from Home Improvement with Tim Allen.) And if I was still in 8th grade she still would have made the crush list, if you know what I mean! Here's the video tease. Look close for a special guest cameo:

Did you see Rebecca Black doing a cameo in the video?

Yeah that's her in the red sitting on the couch.
