While Lifetime’s The Unauthorised Beverly Hills, 90210 movie might have taken some creative license when it came to telling the behind the scenes story of the 90’s drama, star Tori Spelling was on hand afterwards to spill some truths about her time on the show. In a one hour ‘Celebrity Lie Detector’ special, Spelling dished all the '90210' gossip, including which two co-stars she had slept with.

Tori Spelling Tori Spelling appeared on 'Celebrity Lie Detector' to reveal more '90210' cast secrets.

After revealing earlier this week that she had dated Brian Austin Green, the big question was, which of her other co-stars had Tori slept with? While she said nothing ever happened with Ian Ziering or Luke Perry, Spelling did admit to a ‘summer fling’ with Jason Priestley.

"It was our version of, like, a summer romance, the '90210' version and that was it," Tori confessed. "You know, we stayed great friends for the rest of the run, and beyond that, but yeah, we had that one summer fling.”

When it came to her romance with Brian Austin Green, Spelling said it was a "teenage love story” off-screen. "He was a little bit of my everything," Spelling said. ”We grew up together. I think I was always in love with Brian.”

As for her co-star Shannen Doherty, Spelling dished on the actress’s diva-like behaviour, which would eventually get her fired from the show. "It was getting worse and worse," Spelling revealed. Tori then recalled a time Doherty and Ian Ziering got into a heated argument, after the actress had arrived late for an early morning taping.

"Ian turns to her and he said, ‘You are a c--t,'" Spelling said. "She looked at him and she goes, ‘What did you say?' and he said, 'Can't Understand Normal Thinking.’" Spelling said it was after that moment that the cast united in an effort to get Doherty fired from the show.

Spelling also talked about her marriage to Dean McDermott, saying that part of her can forgive her husband for having an affair, but it’s harder for her to forget. "I haven't forgotten it. I'll never forget," Spelling said. "But I guess the truth is that my mind has forgiven him, but obviously, my heart hasn't."
