Interesting, I have never heard the programmer thing.
My assumption was always that she is married to Victor Del Toro ( @boysdontplaywithbarbies on IG), who's a modeling agency director (9 years at Elite, which was where Kara was signed), and her frequent photographer if you look at his IG. He appears to be pretty reclusive and private, but once in a while one of them will post a story where Kara is sitting a dinner table or something and he is tagged, or he will post a story just of her sitting at his presumptive table, etc. I was always under the impression (and I think I read on this site maybe) that they are in an open relationship but that they are married. As career businessman in the modeling biz, I'm sure he is aware that a model without a ring on her finger or a guy on her arm is a better position to be in, from a career standpoint. I suspect that is why she is not usually out with him, or photographed with other guys.
My assumption was always that maybe he discovered or signed her in the beginning of her career and locked her down right away... But that they agreed to be open, at one point or another.
