DONNY OSMOND and VALERIE BERTINELLI are hangin' at the very first OPRAH Store in Chicago!

The former teen stars spent a little quality time right before Valerie went on with Lady O to talk about her new motivational book, Losing It: And Gaining My Life Back One Pound at a Time, which chronicles the "One Day at a Time" star's tumultuous 24-year marriage to rocker EDDIE VAN HALEN and her struggle to maintain a healthy self-image before her life-changing experience as a spokesperson for JENNY CRAIG.

Valerie has lost 40 pounds on Jenny, and the news of the day is about how Valerie's pal KIRSTIE ALLEY is no longer a spokesperson for the weight loss company.

"I know, I don't want her to leave," Valerie tells Donny. "I'm gonna bribe Kirstie, have her come back."

Donny's sister MARIE will have an all-new talk show on TV soon, and Donny asks Valerie if she would ever want to be back on series TV.

"In a heartbeat I would do a sitcom, I would love to -- talk show, that's a lot of work," she says, "but now I can't do a talk show -- Marie's doing one!"

Would Valerie ever follow Marie's footsteps and go on "Dancing with the Stars"?

"No thank you, too hard, never do that; come on, I don't want to work that hard," she protests. "Even if I get married again, I don't know if I'm gonna dance at my wedding. I don't know, I'm not a dancer."

Valerie's appearance on "Oprah" airs Monday, and Oprah's new store is located right down the street from Oprah's Harpo Studios on Chicago's Near West Side.
