Who? Serbian actress.
Real? No, just a hoax starring a lookalike.
Three different celebrity sex tape list pages include this paragraph: “Serbian tabloid claimed that Maja Mandzuka, Serbian actress, shot a porn movie, and published few screenshots. It was soon discovered that the screenshots were from a mainstream hardcore porn movie, and the actress in the movie was not Maja but some unidentified porn actress.”
The identical wording leads me to believe that the paragraph was cut-and-pasted from an old version of Wikipedia’s celebrity sex tape list.
I have no idea who Maja Mandzuka is, or whether she made a sex tape, or which pornstar or porno flick provided the lookalike, or when or how the rumor got started. The fake lookalike video still circulates online if you’re interested.
Here are a frame from the sex tape and a real photo of Maja Mandzuka.
Trousers around the dude’s ankles in the shower is a very sexy touch.
