Noah Cyrus stars in gruesome PETA ad against animal dissection

Miley's Sister Poses in a Shocking PETA Ad

It turns out Miley isn't the only Cyrus who knows how to shock people with bizarre photo-shoots.

Miley's 15-year-old sister Noah Cyrus has teamed up with PETA to appear in a disturbing advertisement for the organization that features the teenager as a lifeless corpse being dissected in a high-school classroom lab.

The ad shows Noah's chest cracked open and peeled back revealing her organs, mirroring the common high-school biology project where students are made to vivisect frogs and other small animals.

The ad reads, "I am not a classroom experiment. Neither are cats, frogs, rats, pigs, or other animals killed for dissection. Please choose not to dissect."

Noah also appeared in an online video for the organization where she encourages students to refuse to take part in the classroom activity.

"If you feel weird about dissecting something, say 'no.' I would totally say, 'I'm not cutting into this animal.' I would never do that," Cyrus explained.

She also spoke about the benefits of digital dissection computer programs that can serve as a viable classroom alternative, saying, "You'll learn so much more off of the computer. If you have the other option, why not take it? You should ask your teacher for other human alternatives."

Recently, PETA has also started a protest of the romantic drama The Longest Ride for its depiction of professional bull riding. Check out the video below to hear what the film's stars, Scott Eastwood and Britt Robertson, had to say about the organization's protest.
