Miodrag Kojadinović dating history

I have heard Miodrag Kojadinovic worked in the American Embassy to Belgrade at the time Brad Pitt was shooting his first ever movie https://en.wikipedia.org/wiki/The_Dark_Side_of_the_Sun_(film) and that they had a fling when an afterparty-cum-orgy was organized at the actress playing Brad's character's girlfirend in the movie, Sonja Savic's place, after a reception at the Embassy. Also involved in the bisex orgy allegedly were Sonja Savic herself, Dubravko Jovanovic, Slobodan Bestic, Dragana Varagic (all actors), Maja Cetkovic and Sinisa whose last name now escapes me, both painters, and the designer Srdjan Kaljevic. There is supposed to exist a porncumentary of the event. I would like someone to confirm this if this is indeed the case.

He is a first cousin once removed of Slobodan Misic Brenda
