Barbara Walters: Star Jones Made Us Cover-up Her Gastric Bypass

"She decided to have a gastric bypass operation, but then she decided not to tell anybody," Barbara Walters said in an interview with Oprah Winfrey airing Tuesday.

"Then we had to lie on the set everyday because she said it was portion control and Pilates," Walters said. "Well, we knew it wasn't portion control and Pilates."

Winfrey responded, "We in the audience go, that's some damn Pilates teacher!"

Walters – who is on a press tour for her memoir, Audition, in which she admits to an affair with a married senator in the '70s – also told Winfrey she has no regrets over on-air spats with former View co-host Rosie O'Donnell.

Tell Us: Should the View co-hosts have kept the lie going?
