Miley Cyrus' teen sister Noah Cyrus is entering the spotlight next with her provocative advertisement for PETA2.

Cyrus, 15, is teaming with the organization to speak out against animal dissection in classrooms in an advertisement.

The advertisement features a pale Cyrus lying on a hospital table with her body cut open and organs on display. The text reads, "I Am Not a Classroom Experiment. Neither Are Cats, Frogs, Rats, Pigs, or Other Animals Killed for Dissection. #DissectionKills."

Cyrus chose to model for the ad because she is a self-proclaimed animal rights activist.

She is working with PETA2 to spread awareness of "more humane" ways to learn about the insides on animals, such as through a digital computer screen.
