Miley Cyrus has become the latest celebrity to join the No H8 campaign.
Since Proposition 8 passed to ban same sex marriage in California, No H8 has silently campaigned against the ban.
Celebrity photog Adam Bouska and his partner created the campaign, using photos to protest.
The photos feature celebs with their mouths duct-taped.
The tape symbolizes the voice of marriage equality being silence.
