"It's absolutely not true," Hart tells ET's Kevin Frazier. "It's Miami, the clubs close at 6 a.m., so I was actually going home early."
Hart's comment comes after photos and video surfaced early this week of him with other women outside of a Miami Beach hotel at around 5 a.m. on July 3.
This isn't the first time Hart has been accused of cheating. His first wife, Torrei claimed Eniko was his mistress during their marriage, and in an interview with ET earlier this year, Hart was open about his part in their split. "With my ex-wife, I was really real about what I did," he said. "I messed up."
Hart appeared to address the new cheating allegations on Wednesday, posting to Instagram, "At the end of the day, you just gotta laugh at the BS."
