Part of Me (2012)

Katy Perry wears several short outfits that reveal nearly bare legs and some cleavage. In one dress, a short rifle barrel is attached to each breast area and these shoot out whipped cream or thick soapsuds. One outfit also reveals partial buttocks.

There are a couple of instances of the skirts of female backup dancers flying up to reveal briefs.

The star's mother looks horrified at a song, "I Kissed a Girl" (the repeating lyric is, "I kissed a girl; I liked it"). She also says she will not watch Perry on TV if Perry has half her clothes off.

A female singer sings repeatedly, "Are you brave enough to let me see your peacock?" while backup singers repeat "peacock" 20 times and we see adults in the audience laughing.

A female trainer stretches a singer's thigh muscles. Staffers watch and laugh, saying the action looks inappropriate (like being in stirrups in an OB-GYN office).
