Lauren Dunn: Married At First Sight bride posts her own topless photo after revealing she was the victim of revenge porn

Married At First Sight bride Lauren Dunn has revealed she was the victim of revenge porn when her ex-boyfriend posted a topless photo of her in Perth “years ago”.

The 33-year-old PR expert shared several videos on Instagram on Thursday and said that “trolls” were now trying to blackmail her for money by threatening to further distribute the nude photos.

However, Lauren said she would not have sent the topless photo to her former partner if she didn't think it would be seen, so she decided to post it on her own Instagram.

“I have a little story for you. About 10 years ago, my then ex leaked a topless photo that I had sent him,” Lauren explained to her followers.

“In the end, everyone got it. I mean, everyone. It was everywhere, but it wasn't a big deal. We all have tits and nipples, so whatever.”

Although Lauren is indifferent to the leaked nude photo, she says she is bringing the matter to light because she has recently received messages from people who have the picture.

In one of her stories, she shared the following text message: “Hey, I have some photos of your boobs, Lauren.”

When the reality TV star responded with “What, Wtf?” they revealed: “If you [sic] “My ex leaked your nude photos in Perth many, many years ago.”

Lauren then told her followers: “There were even some troll accounts trying to blackmail me with it, but it was like I was posting it. I look good. I'm posting my own nude photo.”

The blonde beauty then made good on her own promise, sharing a topless photo with a black bar over her nipples.

In the picture, Lauren, who rose to fame on MAFS this year, showed off her incredible figure as she posed for a selfie in front of the bathroom mirror wearing only white underwear.

The PR expert shared several videos on Instagram on Thursday and said that “trolls” are now trying to extort money from her by threatening to further distribute the nude photos.

However, Lauren said she would not have sent the topless photo to her former partner if she didn't think it would be seen, so she decided to post it on her own Instagram.

“If you didn't have the photo like everyone else in Australia, you do now. Obviously I can't post nipples on Instagram, but use your imagination,” Lauren said.

Lauren then took a more serious tone, warning her followers not to post nude photos of others as this could be considered a criminal offense in Australia.

She then released another video telling her fans to be proud of their bodies and not to let anyone blackmail them.

“If you have great boobs, take them out, put them on the Internet and show them to the whole world,” she joked.
