2U David Guetta Feat. Justin Bieber
Katy Perry is releasing Last Friday Night (T.G.I.F.) as her next single.
It will be the fifth track from Teenage Dream single and here's the geekish artwork.
Yes, Katy may be dominating the sexy and best dressed women charts but she's opted for the geeky look here.
The look is similar to Katy's nerdy appearance at 2010 Teen Choice Awards.
Katy Perry is currently in Australia on her world tour with more gigs lined up for America this summer.
Today Roberto's been asking you to recreate that geek look....and here's what you managed.
