Beyoncé’s Searching for a New Sasha Fierce

Jimmy Fallon is psyched to take over for Conan on Monday as host of NBC’s Late Night. He already has plans for unusual musical acts in store: “How many times can you see Kanye?” he quips. Busta Rhymes feels for Rihanna, and Beyoncé is offering $2,500 and a video appearance on her upcoming tour to whoever sends in the most bootylicious reenactment of her Single Ladies dance moves. Start shakin’, ladies! (Oh, who are we kidding. A dude is gonna win this.)

Miami Fontainebleau owner Jeff Soffer is sad because he can’t open a casino in his swanky hotel, but snuggling up to Elle Macpherson at the Little Nell in Aspen probably cheered him up. The Oscar gossip just keeps on coming: Ben Stiller had a meltdown at the show’s rehearsal, and Leonardo DiCaprio, Robert De Niro, and Joe Pesci chatted about co-starring in an Italian heist movie at Harvey and Bob Weinstein’s Oscar party. Meanwhile, Chinese censors cut Steven Spielberg from their re-airing of the Oscars, perhaps as payback for Spielberg quitting as artistic adviser to the Olympics in Beijing, and Tom Cruise fired his publicist sister, again. As a consolation prize for not taking home an Oscar, Axe deodorant sent Brad Pitt a ten-pound, solid-dark-chocolate bust sculpted to look just like the actor.

Kate Bosworth is taking a stab at producing. Liz Smith bids her Post readers adieu. Rocker daughter and “painter” Alexandra Richards teams up with Victor Demarchelier (son of Patrick) for an art show tonight and after-party at 1Oak. Mick Jagger was seen with his two youngest kiddies at the Primary Stages play Shipwrecked. Speaking of kids, Madonna drags Brazilian boy-toy Jesus Luz with her to Kabbalah services.

Designer Valentino Garavani’s boyfriend pulled the fashionista to safety after he tumbled into the street trying to escape a swarm of paparazzi in L.A. And just when you thought those Real Housewives couldn’t get any classier, Orange County wife Jeana Keough has become the spokeswoman for cellulite treatment SmoothShapes. Also, Star Jones’s ex, Al Reynolds, is looking to get hitched again. To a woman.
