"She doesn't talk to me anymore," Spelling said of Thiessen on Ryan Seacrest's KIIS-FM radio show Monday, while promoting her latest book Uncharted TerriTORI.
In fact, Spelling, 37, says with the exception of Jennie Garth, she is not in touch with any of her former 90210 pals.
"All my cast members hate me," she says. "People say, 'Do you mean during 90210?' I say, 'No, we were great friends during 90210. We were friends after 90210.' They all came to my first wedding."
But according to Spelling it all changed after she got remarried. "All of a sudden I marry Dean [McDermott], and I don't know what happened," she tells Seacrest. "I lost all my cast members."
For the record, Seacrest tells Spelling that Thiessen "never said anything bad about you – I think she likes you a lot."
Of the friend drama, Spelling adds, "It's my perception, and nonetheless, it's a fun story."
