Tori Spelling took a lie detector test that revealed how she had an affair with "Beverly Hills 90210" co-star Brian Austin Green.

Entertainment Tonight reported about the said polygraph test, which took place amid the actor's highly publicize divorce with ex-wife Megan Fox.

In an episode of Lifetime's "Celebrity Lie Detector," the 40-year-old actress was cornered by host Louise Roe if she had sexual relations with any of the actors from "Beverly Hills 90210."

"Yes," the mother-of-four admitted.

Tori Spelling is currently married to actor Dean McDermott and has been open about their marital woes as documented in their reality series "True Tori."

Louise Roe noticed that Tori Spelling got emotional following the lie detector question. The host then prodded and got the actress to admit that she was referring to leading man Brian Austin Green, who is currently in the middle of divorcing sexy star Megan Fox after five years of marriage.

"Brian and I were the youngest," Tori Spelling recalled.

"He would tease me, he teased me a lot. He would always come up to me and say that I had peach fuzz."

"I was like 'Great! There's all these extras around me, hot girls'... And I was just really hoping he likes me," she confessed.

Tori Spelling's lie detector confession came after Megan Fox and Brian Austin Green announced that they are separating after being together for a total of 11 years.

According to a report from Daily Mail, insiders claimed that the "Transformers" actress wants to focus on her career, which made her husband feel that she was neglecting their marriage and two children.

"They fight about her career," an insider shared. "She was obsessed with getting roles."

Us Weekly also reported Megan Fox and Brian Austin Green have been separated for months, particularly after the actress became busy with promoting "Teenage Mutant Ninja Turtles."

"Megan has separated from Brian," an insider said. "They decided on it six months ago."
