'Raising Hope': Katy Perry Is Sabrina's Mean Prison Guard (VIDEO)

Katy Perry is considered one of the most beautiful women in the world of pop music, but she certainly wasn't afraid to get a bit gruff for her guest starring role on "Raising Hope" (Tue., 8 p.m. EST on Fox). Donning a terrible and terribly big curly wig and a mustache, Perry played Rikki, the guard assigned to Sabrina in jail.

Sabrina got arrested for a peaceful protest that turned violent when the police refused to arrest her, so she kicked one of them in the family jewels. Once in prison, she found a new kind of torment in the form of Rikki, who told her that they'd once been good friends, but when Sabrina got popular later in their schooling, she dropped Rikki.

So Rikki set out to make Sabrina's life in prison a living hell, dropping her food on the floor and taking her pillow and bedsheets. In order to try and get back on her good side, Sabrina had to recite the pledge for the Little Beavers club and even try to sell cookies to the other inmates, wearing the same Little Beavers uniform she supposedly wore when they were friends back in the sixth grade.

After Virginia's newfound friendship with the mayor -- which spawned after she saved her from herself twice -- led to Sabrina getting released from prison, though, Rikki moved on to another female inmate with the exact same story.

Watch "Raising Hope" at its new time, Tuesdays at 8 p.m. EST on Fox.
