Following up the story from yesterday that said Shannen Doherty might join the new 90210, reportedly, we can change that to:

Shannen Doherty will join the new 90210.

A reliable source told E!: "It is happening with Shannen. It's just a question of how long she'll shoot, whether it will be one day or ten, and what the storyline will be, but we are working on it and it is a very real thing."

Moreover, another insider stressed that the diva-like behavior exhibited by Doherty during her run on the original series is nowhere to be found:

"I want to stress that Shannen has been very, very cool through this whole process. We have seen nothing like the behavior for which she was once famous for."

As for Tori Spelling: rumors have been swirling that the actress is no longer appearing on 90210.

In reality, her first air date has simply been pushed back. How come? We'll let Tori explain:

"I'm looking forward to returning to 90210 in a later episode, but I just had my baby three weeks ago via C-section. So right now I have to focus on recuperating, and my first priority is my family."
