Hollywood Exclusive by Marilyn Beck & Stacy Jenel Smith

Reports all over the Internet have Sharon Osbourne poised to thumb her nose at Simon Cowell by joining the U.K.'s "Strictly Come Dancing" — in direct competition to Cowell's "X Factor" show that she left last year. Sharon wants us to know, "That's so wrong.

"I work for Simon on 'America's Got Talent,'" she points out. "He's a great guy, and we have a great relationship." She notes that she didn't take on the other show last year when asked. Now she might. But she says stories that have her getting back at Cowell over her "X Factor" departure amount to "the British press trying to get something out of nothing. There's nothing to get back for."

The fiery personality has already returned to her post as an "America's Got Talent" judge. That show, produced by Cowell, returns to NBC's lineup June 23. As far as "Strictly Come Dancing," she's just about to decide. "I will say I'll do what I want when I want it," she says. "I can't be bought."

Also, she makes the point that "Strictly Come Dancing" — the British counterpart of "Dancing With the Stars" — would be good for her in terms of staying in shape and serving as an example of a fiftysomething cancer survivor with oodles of get up and go.

MEANWHILE: Sharon, whose grueling — but successful — 2002 battle with colon cancer was chronicled on MTV's "The Osbournes," has just become a celebrity ambassador for Stand Up to Cancer. That's the organization behind last year's groundbreaking multi-network, star-laden fundraising event geared toward accelerating cancer research. "I'm just so happy to be a part of something that can bring such awareness to people," says the woman who faced down the disease when it had already spread to her lymph nodes.

Last week, the SU2C initiative announced five research "Dream Teams" selected to receive $73.6 million, collectively, in three-year grants.

Osborne says that as far as cancer care, "I have so many issues with it. In this country, a lot of it is about insurance. They try and run it by the numbers, but you can't because cancer doesn't have a restriction on age." Some insurers, she notes, "say you have to be 50 to be covered for a colonoscopy.

Well, that didn't help a girl of 18 I knew who had colon cancer." She adds, "You have to get these medical research teams to work together. It's not about seeing who is the most clever. It should be a group effort, with each country sharing their scientific finds."

SPELLING TROUBLE: Tori Spelling's mom Candy may be continuing their public feud by going on the radio and blaming husband Aaron's demise on their estranged daughter, but the young star makes it clear she's focused on her career at the moment. Having made a guest appearance this season on the CW's "90210," she tells us stepping back into Donna Martin's shoes was something she enjoyed more than she expected — and wouldn't mind doing again. "It was great, but it was scary at first. I was nervous coming onto someone else's set, even though oddly it was my set originally," she notes of being a part of the original show. "It was pretty cool to be like, 'Oh, my God, I'm Donna again!' When certain chapters of your life end, you feel like that's it, and then you move on. I don't think it ever occurred to me that I would be going back to play Donna and certainly not having the life that I have now."

The mother of two certainly has plenty of other things to keep her busy. "I have the Tori Spelling Collection jewelry line. I have my children's clothing line coming out this fall, which I'm really excited about, called Little Maven. My second book, 'Mommywood,' is out right now," says Spelling, who is also currently starring in the fourth season of her Oxygen reality show "Tori & Dean: Home Sweet Hollywood." "We've actually extended our brand with Oxygen more. We have a pilot we're doing with them, and we have a movie of the week we're going to do together. Then we're going to turn my book 'Mommywood' into a Web series." And after that? World domination!

LOOKING FOR TROUBLE: With Reese Witherspoon, Owen Wilson and Paul Rudd lined up for his next big-screen romp, filmmaker Garry Marshall is now choosing among candidates to play Madison, described as a 10-year-old girl with a mean streak who determines that Valentine's Day is the ideal time to take revenge on her enemies. The yet-untitled flick starts shooting next month.
