Friends of Camilla are not invited to The Wedding. Not! Even good buddies blew it. Ask not how I know. I know. If you’re a chum of Kate, Wills, Charles, Elizabeth (providing she has girl-talk bridge- playing cronies), Philip (forget it, he has no friends) — OK, you got the invitation. A Camilla pal? No. No. A thousand times no. A better chance is attending Ruth Madoff‘s next wedding.

BOBBY Cannavale. So hot you’d think he has fever. Great in the film “Win Win” with Paul Giamatti. Great in the show “The Mother f**ker With the Hat” with Chris Rock. Great — so I hear — in a romance with Sutton Foster of “Anything Goes.”

“Who knows why things happen?” he says. “I’m 41. I can’t believe the hype. I just do my job. I was red-hot before for five minutes, then it disappeared, so this show’s until June. Next I don’t know. I have nothing. I’m just a working stiff.”

He swatted my complaints about theater’s foul language: “I grew up like that. I don’t mind those words. If used correctly, I think it’s poetry.

“Broadway’s too much the same old thing. Irish and English dominate. It’s monopolized by the wealthy. Again ‘The Importance of Being Earnest’ for old people? Pay $15 to see new theater in downtown crappy fleabags? At our stage door, people tell us they’ve never seen a play before. We need something for everybody.

“Chris Rock’s seen four legit things his whole life. One was ‘Pearlie.’ He said, ‘I love this because it’s not a play play.’ Bus drivers love it. Regular working classes who are struggling won’t feel alienated.

“I’m not exactly around the house practicing curse words. I’m divorced. My son Jake, 16, lives nine blocks away. Got a great voice, taking lessons, wants to be a musician. He’s with me half the time, backstage between shows, and I tell him not to use bad language.

“I like playing super-desperate types who fight for what they want. I guess I’ve just got that inside me. In ‘Win Win’ my character was desperate, hanging out at his ex-wife’s house. I’m not rich, so maybe that’s why I never yet played a rich guy.”

OK, so, Sutton Foster.

“Best thing ever happened to me. I’m head over heels in love 100 percent. Relationships in life are hard. We spend lots of time together, but it’s like a secret that she sings and dances, because I’ve never once seen her even humming. Although she’s the tops, I can’t say too much. I don’t want to jinx it.”

UNDERSTAND I can’t confirm this. Whoever wants to follow this up, lots of luck. I tell it because one can’t ignore the story in case there’s some truth.

Seer John Cohan, who often seems to know tidbits after celebrities pass on, claims Elizabeth Taylor was a client since the ’60s. They’d have phone visits. Says the psychic: “She revealed a secret that’s haunted her for years.

“A child out of wedlock. The studio and her mother gave baby Norah away. Money was exchanged. Living in Ireland, the child, resenting the mother who gave her up, wanted nothing to do with Elizabeth. Having then been with three men, Elizabeth wasn’t sure of the father.

“Elizabeth, guilt-ridden about this always, told me, ‘Say nothing until I’m gone.’ ”

I just saw William Holden, Judy Holli day, Broderick Crawford’s original film “Born Yesterday,” and B’way’s production with Jim Belushi is deli cious. He’s super. It’s super . . . So how will Regis‘ TV split affect his and Kelly Ripa‘s commercials? . . . A Johnny Depp goal is Shakespeare onstage . . . A Robert Downey Jr. comment: “Prison didn’t change me. It’s like high school or being on a movie set. Change comes from within.”

IN Walmart, a can of Mandarin oranges said, “From China.” Other food labels read, “From China.” For a few more cents, a shopper bought the US Dole brand.

Many believe trading of often toxic products, dangerous toys and goods to us should be suspended. We’re dependent on items “Made in China” or “PRC,” which includes Hong Kong. Plastic eggs to celebrate Easter? Real ones benefit our farmers. If 200 million Americans withhold $20 each from such merchandise, a billion-dollar trade imbalance might resolve in our favor.

EMMA Watson, 21, speechless at meeting Matt Damon. Turned red on the red carpet. Lucky the carpet wasn’t green . . . Next generations: Michael Alden and Lizabeth Zin del (Paul Zindel‘s daughter), producers of “High,” co-producing supernatural thriller film “Spiral” by John Buffalo Mailer (Norman’s son) in Provincetown in May starring Mickey Sumner (Sting‘s daughter) . . . Year 2059 headline: Average American’s weight drops to 250 pounds . . . Broadway Cares/Equity Fights Aids’ Easter Bonnet Competition is today, 2 p.m., the Minskoff Theatre, West 45th Street.
