VIDEO : Jason Priestley on Hooking Up With Tori Spelling: 'It's Nobody's Business'

Tori Spelling admitted in a lie detector test that she slept with former Beverly Hills, 90210 co-star Jason Priestley and now he's commenting on her confession. Following the airing of Lifetime's The Unauthorized Beverly Hills, 90210 Story, Priestley responded to tons of tweets from fans who were watching the made-for-TV film, tweeting, "I'm not getting into this... It's nobody's business... Either way..." His statement comes after Spelling spilled the beans about their supposed tryst, which apparently was nothing more than just a short-lived fling.
