Uh oh, new photos have surfaced showing Married At First Sight's Martha Kalifatidis getting cosy with a mystery man.
The controversial reality TV star, who left her boyfriend Michael Brunelli at home to travel around Europe with her pals, was photographed making crude gestures with a man known only as Ali. A quick search through Martha's social media followers shows no sign of a man named Ali.
An onlooker who was also partying in Mykonos told the Daily Mail that the pair were getting "very handsy" and, at one point, Ali placed his hand around Martha's mouth as she stuck out her tongue to perform a lewd gesture.

The spy also revealed Ali was allegedly "boasting" about his friendship with the popular reality TV star, sharing dozens of videos and photos of the pair together to his Tinder profile.
Since rumours began circulating that Martha had potentially moved on from her on-screen husband Michael, the makeup artist set the record straight, admitting "he's a family friend".
Earlier this week, the 31-year-old came under fire when she shared an incredibly provocative close-up photo of her private area on Instagram. While many praised the star for her incredible figure, some argued the photo was "disrespectful" to Michael.
"@mbrunelli must love these photos you post! Don’t get me wrong you’re Hot AF! But you’re not single? Some respect for him? Or $$$ more important."
Earlier this month, Michael revealed he wasn't enjoying all the skin she's been showing online!
After the brunette beauty posted a photo of herself and her pal in bikinis, posing in front of the mirror, one user commented: "@mbrunelli brah she's on vacay alone but ur sketching bro."
FYI, "sketching" is a millennial term for freaking out, or being paranoid.
After noticing the comment, Michael responded, writing: "All good bro I've been doing what any guy does when their misso goes to Europe," he began. "Spending 4 hours a day monitoring her socials for other dudes, then sending real aggressive texts asking who everyone is. Duh."
