The actor says not being loyal to his wife was his 'dumbest moment.'
Kevin Hart is opening up about his past mistakes.
The Jumanji: Welcome to the Jungle star was a guest on Power 105.1 FM's The Breakfast Show on Thursday, where he discussed cheating on his wife, Eniko Parrish, while she was pregnant with their first child together.
"I'm guilty," he confessed. "Regardless of how it happened and what was involved, the s**t that I can't talk about, I'm guilty. I'm wrong."
"It's beyond irresponsible," he continued. "There’s no way around it. The best way to do is just address it, right on. That's Kevin Hart in his dumbest moment. That's not the finest hour of my life. With that being said, you make your bed, you lay in it. You can't say, 'What were you thinking?' Because you weren't thinking."
Realizing what he had done, Hart said he took responsibility and had a conversation with his wife about what had happened.
"You don't plan to f**k up. You f**k up and then you go, 'Oh s**t, I f**ked up,'" he explained. "I'm gonna go home, I'm gonna address it, I'm gonna make my wife fully aware of what's going on in the situation that I have now put us in and I'm hoping that she has a heart to where she can forgive me and understand that this is not going to be a reoccurring thing and allow me to recover from my f**king massive mistake. That's what I'm trying to do not only as a man, but within teaching a lesson to my son."
"You do something wrong, stand in front of your own s**t," he added. "This was Dad's wrong s**t."
Rumors that Hart was cheating first started making headlines in July, when Hart was spotted out and about with a mystery woman in Miami, Florida, while Parrish was eight months pregnant with their now three-week-old son, Kenzo Kash. Two months later, following an extortion scandal, Hart publicly apologized to Parrish, as well as his other two children, son Hendrix, 10, and daughter Heaven, 12, whom he shares with his ex-wife, Torrei.
"Sending so many apologies to my wife & kids," he captioned an emotional Instagram video. "I gotta do better and I will. I'm not perfect and have never claimed to be ...I love you all."
ET caught up with Hart, 38, and Parrish, 33, at the Los Angeles premiere of Jumanji: Welcome to the Jungle earlier this month, where they revealed how they're adjusting to life with a newborn.
"You know, for me, I'm a father of three, but the one thing that you are always just a little scared of is, 'How are my kids gonna receive them? How are my kids gonna receive the new baby?'" Hart explained. "The fact that they broke down crying, hugging him every chance they get to hold him... I'm on a different level of life right now."
