Kristin Davis, the ex-madam who supplied call girls for Eliot Spitzer when he was attorney general and governor, has gotten herself on the November ballot. Davis procured 23,000 signatures – more than the 15,000 required – in support of her candidacy as an independent challenger to Andrew Cuomo. She’ll be the first woman in New York history to run for the office while on probation (for one count of promoting prostitution in the third degree). Among those who signed in support of her pro-marijuana, pro-gay marriage candidacy were comic Prof. Irwin Corey and “True Blood”s crazy vampire king Denis O’Hare.

You’re never too old for a slumber party. Actor Richard Gere was overheard at the Chanel J12 Marine benefit dinner at The Crow’s Nest in Montauk on Saturday, saying what a “great” time he was having crashing at his buddy Jimmy Buffett’s Montauk home for the weekend. Both Gere and actress Anjelica Huston were houseguests of the “Margaritaville” singer, and joined Gayle King, Rachel Weisz, Mark Ronson, Julian Schnabel and Carey Lowell for cocktails on the beach at the casual-chic establishment before dinner, which benefited the Surfrider Foundation. Many of the guests had worked up an appetite after a day of Chanel-sponsored paddle-boarding in the Atlantic, where VIPs got lessons from Laird Hamilton and his hottie wife, Olympic volleyball player Gabrielle Reece.

Two music superstars checked out the legacy of a third when Prince and Bruce Springsteen (separately) caught “Fela!” at the Eugene O’Neill Theater on Thursday. A source tells Gatecrasher that the Boss and his wife came with their kids and godson, and went backstage afterward. Prince liked the show so much he told his pal, comedian Chris Rock, to see it. Rock caught the Tony-winning musical the very next day, telling the publicist, “Prince told me to come.” We hear the pocket funkster is planning to return after Sept. 14, when Patti LaBelle will join the cast.

Erika Jayne knows the value of mystery. Judging from all the gay boys sporting Jayne’s promotional T-shirt around Fire Island, the dance-pop provocateuse gained a few fans at the Aug. 14 Ascension beach party in the Pines, where she sang her new single “One Hot Pleasure.” This past spring, she was a hit at the all-girl Dinah Shore Week in Palm Springs. And none other than actor, rocker and celebrity satyr Michael Des Barres has composed an erotic poem for Jayne that proclaims her “pure, tarnished, electric dirty beauty.” Jayne says she appreciates all the attention, but when it comes to her personal life, she’s happy to keep us guessing. Not only is it “a great part of fantasy,” she says. It’s also “show business.”

“The Hard Times of RJ Berger” actor Paul Iacono and his posse got kicked out of Roseland Ballroom’s VIP section on Thursday after they repeatedly spilled beer on concertgoers (including a reporter for this column) and otherwise behaved obnoxiously at the Sounds Like Paper 2010 Ke concert. As security led him away, Iacono was heard protesting, “But I have a show on MTV!”
