Will she guest star on the popular spinoff?

Tori Spelling is giving her thoughts about the new "90210" -- and revealing the secret behind her trim post-baby body!

Speaking to OK! magazine at the Silverspoons Pink Party Luncheon in recognition of breast cancer awareness, Tori says she's adopting a wait and see approach to a possible guest role on the new "90210."

"Yeah, we'll see. I'm a big believer in what's meant to be will be, so if it's meant to be it will work out," she says. "I watched it and I think it's so cute. The new cast is so cute."

Of course Tori is busy with her own projects and will get back to work on "Tori & Dean: Home Sweet Hollywood" soon. Though she's looking slim and trim, she reveals her post-baby body secret: Spanx!

"I haven't lost the weight yet! I'm wearing Spanx," she says. "I just stopped breastfeeding so now I can start a diet program. Getting back to working out is the hardest part but we have a really active lifestyle."

Part of that active lifestyle is chasing around her firstborn son, now a year-and-a-half. But it helps keep her arms poppin'!

"Carrying the babies takes care of that," she says. "Liam is so big now and he still wants to be carried everywhere!"
