Meteor freaks, beware! There's a slippery new villain hitting the CW's Smallville (Thursdays at 8 pm/ET) in the form of Tori Spelling. So we went right to the Beverly Hills, 90210 grad for the scoop on her super guest spot.

TV Guide: Rumor has it you're playing a gossip columnist, which is kind of funny considering....Tori Spelling: [Laughs] I love it. I thought if anyone should play a gossip columnist trying to get the dirt on innocent people, it should be me! [Laughs] That's my life every week.

TV Guide: And you get to have superpowers? Spelling: Yeah. My character has Kryptonite powers…. So I can turn myself into water. Tom Welling directed [the episode], and that was great. It's only his second time directing, and he was really hands-on. You always want a director who will work with you on your character, and Tom was all for that.

TV Guide: Smallville, that yard sale of your old furniture, a book and reality show in the works. Busy much? Spelling: [Laughs] It's so funny. When you're an actor and not working, it's like, "Oh god, I'm never going to work again!" Then I got pregnant [by newlywed husband Dean McDermott] and all of this work came... when I'd be fine not working!

TV Guide: What will your book be like? Spelling: When I was doing So NoTORIous, I realized I had all of these funny stories to tell that people would get a kick out of. Things they wouldn't believe that had happened to me.

TV Guide: So it’s something fun?Spelling: The last thing I wanted to do was a tell-all. I’m a big David Sedaris fan; I love his voice and his sense of humor. He tells stories, brilliant stories. So it’ll be in that vein.

TV Guide: When you're out in public, do people just start screaming, "Donna Martin graduates!"? Spelling: Of course! I've heard that for years. But it never gets old. [Laughs] It's still funny.

TV Guide: So what's the weirdest thing a fan has said to you? Spelling: It's more along the lines of people talking about you like you're not there. They think celebrities are deaf. Or they'll point right at you. It's like, "Hello, I see you. Just say hi!"
