The 42-year-old actress opened up in a Lifetime special that aired over the weekend.
Tori was hooked up to a lie detector and replied “yes, but I’m not going to tell you who it is” when asked if she had sex with anyone from the original cast. When asked if it was Jason, she replied “yes.”
“It was a summer fling. It was off-set. It was our version of a summer romance,” Tori said. “The 90210 version. And that was it, and we stayed great friends for the rest of the run and beyond that, we had that one summer fling.”
When a fan asked Jason if it actually happened, he tweeted: “I’m not getting into this… It’s nobody’s business… Either way…”
