Gayle King has insisted she has "healed" and "moved on" from her ex-husband's infidelity.

The 71-year-old broadcaster recently spoke about the devastating moment she found William Bumpus cheating on her with a close friend back in 1990, prompting the attorney to issue an apology for his behaviour, and while the CBS Mornings host "appreciated" his response, she insisted enough time has gone by for them to have got over the hurt.

She told TMZ: "I was surprised that you guys got him. A, that you found him, that's number one. And B, that he was even talking. Because he never talks. So, I was surprised, but I can also say I appreciated what he had to say.

"This happened so long ago that we have both healed, we've both moved on. And the reason why I can talk about so candidly, to be honest with you, is because it has been so much time that has passed. And I'm in a really great place, and so is he."

Gayle has also been touched by the way other women responded to her story on the Call Her Daddy podcast.

She added: "What has really gotten to me is the reaction from other women--that's the thing that has touched me more than anything.

"I want them to know: It's a very big club, none of us want to be in it, but the beauty is you can go through it and you can come out the other side. And you can really be okay."

After Gayle's interview was released, William offered his "deepest apologies" to his family and insisted his ex-wife had "every right" to speak about the scandal.

He told TMZ in a statement: "My deepest apologies to Gayle, to our daughter Kirby and her husband, Virgil, to our son William and his wife, Elise, and to our three grandchildren, for the pain I caused decades ago. Those actions were mine.

"I have long owned [my actions] -- including publicly in my own words in 2016, which still stand.

"Gayle has every right to share what was a painful chapter that changed the trajectory of our marriage and our family nearly 40 years ago.

"I respect her right to tell her story, and that's where I'll leave it."

William is "endlessly grateful" to Gayle - who he divorced in 1993 - for their time together and their subsequent co-parenting relationship.

He continued: "She gave me two of the greatest gifts of my life -- our daughter Kirby and our son William. It was Gayle who encouraged and supported me through getting my Yale Law degree.

"And it was Gayle who chose, with me, to co-parent successfully from the very beginning -- a testament to our shared commitment to our children above all else, and now our grandchildren. The love and camaraderie we forged in that work have carried us all these years."

The attorney noted he and Gayle are "in a good place" today and he will always be a "genuine admirer and fan" of his ex-wife.

He concluded: "As a private person by nature, I will admit that during our marriage I did not fully appreciate Gayle's public life -- I wanted ours to be more private, and that was something I wrestled with, and no reflection on her true talent and abilities.

"I am proud to have had a front-row seat to Gayle's remarkable success, and I remain a genuine admirer and fan.

"I continue to work at being the best version of myself, grounded by the friendship, encouragement, and support of Gayle over the years, by the love of our grown children and our grandchildren, and by the daily privilege of raising Poet as a single dad. That is where my focus remains -- on my family, on my clients, and on the work ahead."

Gayle had recalled the shocking scenario she encountered when she returned home with their kids after a flight was cancelled.

Speaking on Call Her Daddy, she said: "He comes flying out of the room, and he's got a towel on, he goes, 'You can't come in.'

"'What do you mean I can't come in? What are you talking about?' He goes, 'You can't come in. Someone's here.' "

Gayle searched the house because she "didn't believe" what William had told her.

The broadcast journalist said: "I get down, and there they are - or there she is cowering behind the door in my towel. It was a nice bath sheet.

"I said, 'I can't believe that you are here, and that you are doing this. I thought we were friends,' it sounded so pitiful."

Kirby and William Jr. were outside with their nanny at the time, and Gayle asked for them to get away from the house so they did not see their dad and the woman, whom her children knew and referred to as "aunt".
