Reality star Spelling confessed on "Celebrity Lie Detector" that she had slept with two co-stars, Priestley as well as Brian Austin Green, who played the character of David Silver on the show.

The 42-year-old star told the show's host the fling with Priestley was the couple's version of a summer romance, "that was it, we stayed great friends," Spelling said.

According to Entertainment Tonight, Priestley has neither denied nor confirmed Spelling's disclosures publicly. However, the 90210 heart throb told followers on Twitter, the matter was nobody's business.

Priestley tweeted  saying that he had not watched Spelling's much talked about episode and told followers he was not interested to find out details either.

Spelling's appearance on the show has been a direct result of the renewed interest being generated by Lifetime's "The Unauthorized Beverly Hills, 90210 Story," where behind-the-scenes happenings of the show are featured.

Priestley, who was not happy about the Lifetime show, said on Twitter his recent negative comments are directed only towards the biopic and Spelling's lie detector disclosures and not the 90s show.

Meanwhile, during Spelling's "Celebrity Lie Detector" interview she divulged details of being involved in having co-star Doherty fired from the show, which was produced and created at the time by her father, Aaron Spelling. Priestly, however, was quick to defend Doherty's character saying, "Shannen and I will always be friends... Been through too much together..."

According to Us Weekly, Spelling's revelations about Doherty referred to the latter's behaviors on set. Spelling said she witnessed a confrontation between Doherty almost had a fist fight with fellow co-star Jennie Garth.

Spelling said that the tension had been so intense she called her father and asked him to have her removed. Subsequently, Spelling said she regretted being part of a group that cost another person their livelihood. She added that Doherty was in no way a "horrible" individual and said she had been one of her closest friends.
