Ben Foden broke his silence after cheating on wife Una Healy during an emotional segment on Celebrity SAS: Who Dares Wins.
The rugby ace said he will never stop loving his ex-wife and wishes he hadn't hurt her like he did.
He opened up during the Stand Up To Cancer special.
Foden was accused of cheating on singer Una with PR girl Becky Milne just days after the birth of his second child Tadhg, now three.
Former Saturdays star Una publicly announced last summer she had called time on her marriage to her husband, 33.
Ben, who is now dating fitness fanatic Miriam Murphy, opened up about his divorce on the show.

He said: "My life's a bit of a mess. I'll always love Una. She's my first love and the mother of my kids.
"I never meant to hurt her in the way I did.
"I think it's quite appropriate to do a course like this to put some perspective on everything."
“At the same time, it wasn’t the only reason for our divorce to go through.

“It’s not ideal, but we’re very amicable, we’re getting through it, we’re not the first people in the world to get divorced. We’ve got two little kids we adore.
"At the moment anything that’s published about me is never very good and pretty rightly so because I was the one who committed adultery.
“It’s hard because I’m away from my son and daughter.
“But I know they’re in a great and loving environment with Una because she’s a great mum. We never argue about that.”
