Jason Priestley Jason Priestley

Jason Priestley won't be following Tori Spelling's lead in spilling details about the offscreen relationship they allegedly had when filming Beverly Hills, 90210.

After Spelling took a lie detector test for Lifetime this weekend and admitted that she and Priestley had a "fling" one summer while filming the show, fans asked Priestley via Twitter to confirm her comments.

"I'm not getting into this... It's nobody's business," he responded.

(Spelling also confirmed that she and co-star Brian Austin Green were romantically involved at one point, and that she once got a kiss from Luke Perry.)

While interacting with fans on Twitter, Priestley claimed that he didn't watch either Spelling's lie detector segment or Lifetime's The Unauthorized Beverly Hills, 90210 Story, but clarified that he has no negative feelings towards the original series.
