During a Tuesday appearance on the Ryan Cameron Morning Show, Stewart reiterated that he is not gay.
"I'm not on the down low," Stewart told Cameron. "I'm a 100 percent man. I don't do no homophobic. There is nothing about no dude I see."
During the appearance, the former Steelers QB also addressed allegations that he was arrested in Pittsburgh for indecent acts with a transvestite and how he feels about Porsha now.
He previously addressed the issue in a statement in September.
"I'm very ashamed of my wife for saying something that she knows is not true at all. The rumors have never been true. I'm not gay. It is sad that she would target the homosexual community which often times lacks support to begin with. It is very disappointing that she will do anything and say anything for a minute of so-called fame."
"She can have that life," he said. "I just want to continue to be the best single dad and father that I can for my son."
