Tori Spelling admits to sex with two ‘90210’ costars — but which two?

Donna Martin protected her virginity until the seventh season of “Beverly Hills, 90210,” but that doesn’t mean Tori Spelling, the actress who played her, wasn’t getting busy with her cast members.

In a not-so-surprising lie-detector revelation, Spelling admitted sleeping with Brian Austin Green, who was her boyfriend in 1990 and ’91. “I remember the first time, like, I shook his hand, I had that ... I fancied him,” she tells host Louise Roe in a promo clip for “Tori Spelling: Celebrity Lie Detector.”

Yes, that is the name of a real show.

Then Roe pushed for more, asking if she’d knocked boots with more than one of the guys on the set.

“Yes,” Spelling said, “but I’m not going to tell you who it is.” Apparently, about half of the reality star’s friends don’t know the answer to that question.

One clue: She confirmed that it wasn’t Ian Ziering, and that’s good to hear, because he’s nine years older than she is; she was 17 when the show hit the air -- and her dad Aaron Spelling was an executive producer.

So was is Jason Priestly or Luke Perry? Time to call the half of Spelling’s friends who do know the answer to that one.

“Tori Spelling: Celebrity Lie Detector” airs at 10 p.m. Saturday on Lifetime after “The Unauthorized Beverly Hills, 90210 Story.”
