This time the self-titled "K Mart Kim" was photographed making crude gestures with a man known only as Ali on her family holiday in Greece. A quick search through Martha's social media followers shows no sign of a man named Ali.
The controversial reality TV star has left her on-screen 'husband' Michael Brunelli at home.

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".
After the brunette beauty posted a photo of herself and her pal in bikinis, posing in front of the mirror, one user commented: "Michael 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."
