"King of the Hill" fans hoped Fox execs would change their minds about canceling the animated series, but star Kathy Najimy, who provided the voice of Peggy Hill, says it's definitely over.

"Isn't that terrible? It's the worst thing in the world. That was the best job I ever had," says Najimy of the cancellation. "I wasn't surprised because they canceled us before and then they brought us back. This time when they canceled us, I thought they might bring us back" -- but it didn't happen. Still, "There's always a chance they could sell it to another network," she adds.

The final episode airs Sept. 13.

The actress-playwright-director-activist has plenty of other things on her plate as she's currently penning a one-woman show and has a guest-starring stint on Lifetime's hit dramedy "Drop Dead Diva" Sunday (8/23).

"Margaret Cho emailed me and said, 'Come do my TV show in Atlanta.' She's a person who, when she says come, I come. I don't even ask what it is. I show up, get in a costume, and do what she says because she's so brilliant," gushes Najimy. "At some point after you're 20, you start caring about the quality of your experience. The last thing I want to do is be involved with egos or stress. There was no drama there except in the script."

The show hit a strong chord with the actress, who has always been an advocate for women's issues. "This show is great for Lifetime. I think people want to support anything that sort of levels the field of all the craziness that's going on with women and their bodies. Brooke [Elliot] herself is such a surprise," she adds. "We're not used to somebody coming from Broadway that we don't know in TV land, and she has such a charming, easy way about her.

"The truth is, it's terribly difficult to play a model who has died and comes back in the body of a normal-sized lawyer. She does it with such ease that we don't question it. I'm a big fan of hers and from what I've read from the reviews, America has really responded to her as well."

FULLY DEVELOPED: It's a different Jennie Garth than we've seen before on Candace Bushnell's Sept. 10-debuting web series, "The Broadroom." "I play a woman executive. That was a fun thing for me -- to step into my maturity a little bit and play someone my age."

Jennie, who's 37, could easily get away with playing years younger, but she's not trying to. She points out that her and husband Peter Facinelli's daughters are now ages 12, six and two.

The couple have been juggling parental duty with their various assignments -- she also has an as-yet-undetermined number of "90210" episodes to shoot this season, while he's busy making the third film in the "Twilight" series, "Eclipse," and will go into "Nurse Jackie" shooting as soon as he's finished.

They have to make their schedules work, Jennie tells us. "We have three little people depending on us. You know, when he's working I take it all on, because I'm not going to leave them with someone else. That's our job."

LIFE IS TWEET: A funny thing happened during intermission at one of the Jonas Brothers' recent L.A. concerts -- when suddenly there was an outbreak of audience members spontaneously flapping their hands at the Staples Center. Turns out it was the work of "Wizards of Waverly Place" star David Henrie, who was there taking in the show (so were teen faves Aly & A.J.) and communicating with his Twitter followers.

The 20-year-old actor instructed his fans who were on hand: "If ur on Twitter scream and wave ur hands like ur on fire." He then shot a photo of the audience from his seat and posted it, then Tweeted, "Wave ur hands and scream if ur in this pic." Others could only wonder what kind of mass insanity was taking hold.

"The Biggest Loser" host and "Days of Our Lives" actress Alison Sweeney is a frequent Tweeter. She tells us, "It's so much fun for interacting with the fans, sharing stories, taking photos at awards, I love it. I get to see their reactions, or watch shows together, or even just talk about Shark Week or whatever."

Naturally, her soap followers are a strong presence. "Obviously, there are fan groups who have different kinds of conflicting opinions about the show and my character's love life. It's great to get that kind of feedback."
