Katy Perry Before & After: Singer Rocks Hair Rollers Before Getting Glam for New Project

Singer was spotted getting ready in her trailer on set in Sherman Oaks

Katy Perry is rocking some rollers.

The singer was snapped on set of a new project earlier today in Sherman Oaks, Calif., with her hair fully pinned in rollers a grey sweatsuit while walking back to her trailer.

But that was all part of the transition to her ultra glam look.

After a little primping, Perry emerged from her trailer looking absolutely flawless. The curlers clearly did their job by giving the star a soft and shiny wave, as she strutted out in a black-and-white printed dress and black heels.

Although details on what Katy was working on have not been revealed, we do know that she was joined by Laura Dern and comedian Amy Poehler.

So, what do you think it might be?
