Forget a guest starring turn.

Tori Spelling is back as a full-time part of the new 90210!

"Donna loved designing and wanted a career in fashion. It'll be fun to explore that storyline," Spelling said about how her character will return. "And, I'm sure fans will be dying to know if she's still married to David!"

We're guessing that answer is no, considering the fact that Brian Austin Green won't be on the series.

A rep for the show said Donna will "own one of the coolest stores in Beverly Hills."

"Donna Martin was such a huge part of my life. It's going to be so fun to work with Jennie [Garth] again and see where Donna is today," Spelling said. "When they say you can't go home again, it's not true. I'm headed back to the zip code I know best and couldn't be happier!"
