Same-sex marriage is still illegal in Australia, but many celebrities (like Chris Hemsworth) are doing their part to join the fight for marriage equality.

Unfortunately, homophobic groups also recognize the power of celebrity influence.

To catapult its campaign against same-sex marriage, one group decided to use Meghan Trainor's face for its "Vote No" ad.

"My vote is NO," the ad reads. "You need to let it go."

Fans were shocked to see Trainor — who has publicly supported the LGBTQ community throughout her career — in an anti-gay marriage campaign.

After a follower brought the ad to Trainor's attention, the singer promptly denied having any association with anti-LGBTQ groups.

She insisted the campaign illegally used her image without her knowledge or approval.

Trainor expressed her love and unwavering support for marriage equality.

"I think a lot of my songs have a very universal message that can apply to different genres and communities, and I'm happy that some can be considered LGBT themes," Trainor told After Ellen two years ago. "I often dedicate 'Close Your Eyes' to my LGBTQ fans during my shows and tell everyone that they should love whoever they want."

She later hopped on Instagram and made her stance on gay marriage crystal clear.
