Prince Albert’s sisters unimpressed with wife

Prince Albert of Monaco’s sisters, Caroline and Stéphanie, aren’t crazy about his wife Charlene — or her taste in music.

Continental sources say both princesses boycotted this year’s Red Cross Ball, which their grandfather founded in 1948, because Charlene insisted on booking her jazz singer friend Diana Krall to perform at the gala in Monte Carlo last week.

Caroline’s glamorous daughter Charlotte Casiraghi, 28, skipped it as well.

With the princesses staying away, so did Karl Lagerfeld, Lynn Wyatt and other regulars. “It was terrible, a disaster,” one partygoer told me. “Very, very boring.”

South African Charlene, who is pregnant with twins, clapped wildly, as did Prince Albert, but the mostly French and Italian guests didn’t seem to understand the music of Krall — a singer and virtuoso on piano.

They would have preferred to hear Shirley Bassey, who was there, or even Gina Lollobrigida, 87, who was on the arm of her 27-year-old boyfriend, Andrea Piazzolla.

Though Lollobrigida’s son, Milko Skofic Jr., is suing to have her declared incompetent before she spends his inheritance, her friend told me, “She’s fine, as sharp as a tack, and very, very happy.”
