'Brady Bunch' Star Barry Williams Still Has Hots For 'Mom' Florence Henderson (VIDEO)

WATCH: 'Brady Bunch' Star Still Has Hots For TV Mom

It was a story of a lovely lady ... but what was it really like behind the scenes of the hit '70s show, "The Brady Bunch"? In this preview clip of "Oprah: Where Are They Now?" on OWN, Barry Williams (Greg Brady) dishes about his legendary "date" with Florence Henderson and reveals he still has the hots for his TV mom.

"Okay, so here's the lowdown on this," Williams says. "I had a crush on Florence Henderson. Like who didn't? And she was twice my age."

Williams says the two shared a common interest in music. "So I took her out to dinner and we talked music and how I might be able to integrate it into my career," he says.

But career talk wasn't all that went on. "I picked her up in my own car and I took her home, and when we said goodnight, I gave her a little kiss. Maybe a little peck -- well, I kissed her lips," Williams says. "Which was like, big stuff for me."

Williams's teen crush never ended.

"I always had -- I still do -- have a great attraction to her," he says. "I like her very much, and I'm catching up!

"So maybe I ought to give her another call," Williams says with a smile.

Williams caused a stir when he first discussed his evening with Henderson in his 1992 autobiography, Growing Up Brady: I Was a Teenage Greg. Henderson has said the so-called "date" was "blown way out of proportion."

The episode of "Oprah: Where Are They Now?" featuring updates from "The Brady Bunch" kids and other '70s stars airs Sunday at 10 p.m. ET on OWN.
