He did not have an affair with Jada Pinkett Smith, his costar on the recently canceled HawthoRNe.
When asked whether there was infidelity in his marriage, Anthony told Nightline, “No, absolutely not.” And the Smith rumor specifically? “When something like that happens, it’s laughable,” he said. “We’ve been friends for years. Jada, Jennifer, me, [Will Smith], for years.”
“It was a flight attendant, it was the pilot – I heard it was this guy sitting next to me in a rehab in Houston,” he adds of the cheating rumors. “I’ve heard it all.”
But Anthony, 42, adds that he understands why the buzz surrounding the split has been so sensational.
“People are trying to peg it on things because it was so shocking,” he says of the end of his seven-year marriage. “It was like, it must have been something.”
