Shannen Doherty was furious when she found out her former Beverly Hills 90210 co-star Tori Spelling made fun of her on her new TV show "Notorious." The star was especially shocked because Spelling had specifically told Doherty she would never say a bad word about her on the series.

She explains, "(Spelling) sent me a tape of the pilot and a very, very, very small note asking me to do the show, promising that she would never say a bad word about me ever, and we used to be best friends, and still care about each other."

Doherty was stunned when friends began calling her to tell her about the on-air abuse after the show aired.

The star explains, "I was on a self-imposed hiatus. I needed time to myself and I said no. I don't know if it was something taken personally or maybe it was 'If we make fun of her, it will bring in the ratings and the publicity.' It did hurt. I hope it helped her. If mentioning my name made people write about it, then great. Good for you. I get it. It's a business."
