Katy Perry Gets Back to Her Roots!

Katy Perry has been rocking a bunch of different hairstyles for the last few years, most notably her short new platinum blonde mom bob that she's been rocking while on vacation in Mexico with her boyfriend Orlando Bloom and their new baby.

The singer is getting back to her roots for this season of American Idol, wearing a long dark brown wig and an animal print dress. But the look didn't last long, Katy was seen wearing a short blonde wig during filming of the next episode where she explained that her fart sounds are coming from her latex dress and not from her butthole.
