In “Jason Priestley: A Memoir” the former “Beverly Hills 90210” star doesn’t hold back from dishing the dirt says Rob Shuter of VH1’s “The Gossip Table.”

Recalling a trip with his TV sister Shannen Doherty he says the pair were flying on a private jet to meet with advertisers when he heard Doherty gripe, “Her butt had barely hit her seat before she said loudly to the PR person, ‘Really? A town car? You send a town car to take me to the airport, not a limo?’"

“I looked on, becoming more uneasy by the minute as she began b—hing about the short notice and the food on board and the temperature in the cabin and everything else,” he continued.

The 44 year-old actor also remembers, albeit more fondly, a former roommate by the name of Brad Pitt.

“Just for fun, we used to have competitions over who could go the longest without showering or shaving,” Priestley wrote. “Brad always won.”

He also reveals that Tori Spelling, his former co-star, sold his wedding invite in her yard sale.

“I happened to be home watching the local news one night, something I rarely got to do,” Priestley wrote. “I saw my very own wedding invitation on screen. Apparently, it had gone for five bucks, including a personal autograph by Tori. She sold my wedding invitation to a stranger.”
