"Oh my god, I'm gonna get in so much trouble for this.”
So Tori Spelling foretold when she revealed on the Lifetime's Celebrity Lie Detector that she slept with two of her former Beverly Hills, 90210 costars: Brian Austin Green and Jason Priestley.
Of Priestley, the 42-year-old reality star confessed, "It was a summer fling. It was off-set. It was our version of a summer romance. The 90210 version. And that was it, and we stayed great friends."

Now, Priestley, 46, is slamming Spelling’s confession on Twitter. First, when a fan asked if he watched Celebrity Lie Detector and had any thoughts on it, he responded, “Didn’t watch...” Another fan asked if he was curious to watch it, and he simply said, “Nope.”
When he was asked directly about sleeping with Spelling, he neither confirmed nor denied it, but tweeted, “I'm not getting into this... It's nobody's business... Either way...”
He was a little more vocal when someone brought up the fact that Spelling also addressed rumors that she sold Priestley’s wedding invitation at a yard sale and apologized for it, to which Priestly tweeted, “Really??!!? I'm shocked!!”

Elsewhere in Spelling’s Lie Detector interview, she discussed getting Shannen Doherty fired from the series in 1994. "I felt like I was a part of something, a movement, that cost someone their livelihood," she said. "Was she a horrible person? No. She was one of the best friends I ever had."
Priestley came to his onscreen sister's defense, tweeting, “Shannen and I will always be friends... Been through too much together...”
“I'm only speaking with negativity about the Lifetime movie and Tori's lie detector...” he later clarified. “Nothing but love for 90210”
