Shaquille O’Neal will be honest. He was the reason his marriage with ex-wife Shaunie Henderson ended.

Speaking to People for a cover story, the basketball Hall of Famer called himself a "d---head" while being married to Henderson, who was on the TV show "Basketball Wives."

"I was a d---head," O’Neal said. "You don’t know how good you got something ‘til it’s gone."

O’Neal didn’t delve into the specifics of why his first marriage ended, but he did note that he wasn’t "protecting those vows."
