Shannen DohertyShannen DohertyOh dear, someone has upset Shannen Doherty.

Which former pal has been making fun of the actress on her new TV show?

The ex-Charmed star was apparently fuming when she found out that former Beverly Hills 90210 co-star Tori Spelling had made fun at her on her show, NoTORIous.

She reckons Tori promised her she would "never say a bad word" about her.

"We used to be best friends, and still care about each other," Shannen explained.

But she was stunned when friends called to tell her about the on-air abuse after the show aired.

IMDB quotes Shannen as saying: "I was on a self-imposed hiatus. I needed time to myself and I said no.

"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."
