According to The Daily Telegraph, Tracey's ex-boyfriend, Patrick Kedemos, a Perth businessman and former diplomat, revealed that the star caught up with him halfway through her "marriage" with Dean.
Patrick told the publication he had caught up with Tracey between October and December 2017, which was around the same time production of MAFS was underway.
He said they started their relationship in 2016 but broke up in June, 2017.
The newspaper reports that Dean is said to have no idea about these chance encounters.
Meanwhile, Patrick revealed he would like to remain tight-lipped about his time spent with Tracey.
“Being a private person, I have consistently abstained from making any comment despite numerous media solicitations regarding several aspects of our relationship.
“She has chosen to live in the public eye, I have not. I wish her well.”
