Actress and reality TV star, Tori Spelling, who is now pregnant with her second child, decided to share some of the secrets from her "Beverly Hills 90210" times with the world, in a new tell-all autobiography.

In her book, the 34-year-old openly discusses about facts from her life as well as her co-stars from the '90s teen drama.

"I spent so many years in the media having people tell stories about my life, so I figured I might as well tell the true stories about my life this time. Nobody's read it! Not even [my husband] Dean!" the actress said explaining why she wrote an autobiography.

Probably the most interesting part of the book at this point is the one concerning on-camera rivals Jennie Garth and Shannen Doherty, who reportedly had a real-life fistfight.

"Shannen had everything, but she could be arrogant and carefree. Jennie [Garth] was outspoken when she thought Shannen was out of line. Sometimes they got along, but there were explosions. Once they got into a fistfight," the book excerpt revealed to People magazine writes.

"A night with [Shannen] meant going to the hottest club and drinking until the early hours. I knew she was a 'bad influence,' but I liked her anyway."

Shocking or not, Spelling also admitted that it wasn't just her character who had a crush on Brian Austin Green aka David, she too was involved with him.

"Brian was the only guy on the show my age. We had something going over the years we worked together. We were always fighting, making up, having fun and hating each other. We were just young."
