Pop singer Miley Cyrus has posed for the NOH8 Campaign, the silent protest which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

The NOH8 Campaign is helmed by photographer-activist Adam Bouska and his partner Jeff Parshley. The pair photograph celebrities and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

In a Facebook post on Monday, the campaign thanked Cyrus for participating in the NOH8 Campaign.

While her official photograph has yet to be released, a behind-the-scenes outtake shows Cyrus wearing little more than a white see-through shirt and a black bra.

Earlier in the month, Cyrus tweeted to her nearly 4 million followers: “It would be a dream come true! I am so passionate about equality 4 all and it would be magical to join forces w @NOH8Campaign.”

Cyrus has previously tweeted in support for marriage equality.

In July, she forwarded a photograph of an equality tattoo on her ring finger with the message, “All LOVE is equal.”
