Actor Jason Priestley reveals behind-the-scenes antics of his former Beverly Hills, 90201 costars Shannen Doherty and Tori Spelling in a new memoir, according to US Weekly.

In his book, Jason Priestley: A Memoir, the one-time heartthrob opens up about his experiences working on the show, detailing Doherty’s opulent preferences and Spelling’s cheap betrayals.

Priestley, 44, recounts when 90210 executives booked the actor and Doherty, 43, on a private plane to meet with advertisers in 1990.

“I could not believe my ears at Shannen’s very first words after she boarded,” writes Priestley, in an excerpt from the book. “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?’ She sighed a very put-upon sigh. I laughed, as I couldn’t really tell if Shannen was kidding or not.”

“But that was just the beginning,” adds the actor. “I looked on, becoming more uneasy by the minute as she began bitching about the short notice and the food on board and the temperature in the cabin and everything else.”

At this time, Aaron Spelling’s soap opera about wealthy teenagers living in Beverly Hills enjoyed high ratings, propelling the young cast, including Jennie Garth and Luke Perry, into the spotlight.

Spelling, 40, attempted to capitalize on this fame, resulting in a negligible profit and hurt feelings.

“I happened to be home watching the local news one night, something I rarely got to do,” writes Priestley. “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.”
