Lady Gaga, Ariana Grande and more join Planned Parenthood's #BansOffMyBody campaign

Nearly 140 musicians signed in support of the goal.

The campaign aims to raise awareness about "the harm of sweeping bans on access to safe, legal abortion and affirm that no one is free unless they control their own body," according to Planned Parenthood.

A full-page ad, featuring the signatures of nearly 140 musicians who've signed their name in support of that goal, can be seen in the latest issue of Billboard magazine.

Others who've signed on to the campaign include Demi Lovato, Halsey, Lizzo, Billie Eilish, Nicki Minaj, Sara Bareilles, Dua Lipa, Meghan Trainor, Sia, G-Eazy, Troye Sivan, John Legend and more.

The campaign, located at IStandwithPP.org, aims to collect a half a million signatures by the anniversary of Roe v. Wade in January 2020.
