Kate Gosselin still wears her wedding ring

NEW YORK — Kate Gosselin said her marriage to Jon would have failed whether it played out in the glare of a TV reality show or not.

"Was (divorce) a product of the show? I feel like it would have happened anyway — cameras on or cameras off," she said.

Appearing on NBC's "Today" Monday, Kate Gosselin discussed her separation from her husband, which was announced in June on their TLC network reality show, "Jon & Kate Plus 8."

Despite their separation, both parents continue with the hit show, which documents the challenges of raising twins and sextuplets.

"In everybody's life, you make sacrifices," Gosselin said, referring to her staying with the show. "Everybody has to work. Everybody has a job. Ours is a very unique job. ...

"I still feel like this is a good thing. It's healthy. And the kids would agree."

Gosselin told "Today" host Meredith Vieira that she still wears her wedding ring for the sake of her eight children, but feels a lot of failure that the marriage is over.

"This is not what any mother sets out for, for her children," Gosselin said, adding, "It's necessary. It has to take place."

She greeted inquiries from Vieira about Jon Gosselin's alleged cheating during their marriage with a mix of vagueness and diplomacy, and said she couldn't recall exactly when he moved out of their Pennsylvania house.

"I think it's very clear that we are two different people at this point, with two different sets of goals," she summed up.

She repeated her past denial of media reports that she had an affair with a bodyguard assigned to protect her for the show.

"There is no affair. There has never been an affair," declared Gosselin. "It's just another crazy rumor. It sells tabloids."
