FAMILY MATTERS: Paul McCartney certainly has no regrets about a gig he's playing next month in Paris. "I'm returning to the Olympia just like Edith Piaf," joked the music legend, in town to support his daughter Stella's show on Thursday. And he has other irons in the fire, too, as he's working on a second "The Fireman" album and writing a guitar concerto. "I'm also working on a photography project, but it's a secret for now," he said. Fellow fashion follower Lily Allen is on the property ladder. "I've just bought myself a house in Queen's Park [in London]," said the singer, seated next to French actress Ludivine Sagnier, who has just finished filming "Public Enemy Number One." "I finally got to play a gangster bitch," she said with a smile.

CANDY LAND: Blumarine, which planted its flag at 56 Avenue Montaigne, hosted a candy-filled inauguration party, attracting a constellation of starlets, including Julie Depardieu and Virginie Ledoyen. "A better location does not exist," said designer Anna Molinari, who cofounded the label with her husband, Gianpaolo Tarabini, in 1977. She said a Miami flagship is slated to open next month and a fragrance is in the works for next year. Meanwhile, following in her father Antoine de Caunes' footsteps, Emma de Caunes said she is about to start directing her first feature film, "Papa Was a Rolling Stone." "It's about relationships between fathers and daughters, what else?" she chirped while chatting with fellow actresses Mélanie Thierry and model Audrey Marnay, who's working on short movie projects. Ledoyen said she's taking time off filming "Mes Amis, Mes Amours." "I'll let you guess what it's about, but I'll give you a hint: something to do with friends and lovers," she joked.

IN THE BAND: There was a medley of musicians in Givenchy's front row Wednesday night as Courtney Love squeezed in next to Kanye West and actresses-turned-musicians Emmanuelle Seigner and Joanna Preiss. "I came over here to buy a house in London," Love said, adding her band is based in the city and she's shooting the cover of her next album there with Sam Taylor-Wood. But it was the huge gold Manga-style diamond-studded pendant around West's neck that was the center of attention. West created the piece with Takashi Murakami, who also designs the rapper's album covers. The two are working on a full collection. "They'll be more accessible, they won't be all diamonds," said West, adding there's still work to do on the prototype. "The eyes are not perfectly done. Murakami cringes when he sees the eyes." Preiss was all nerves ahead of her DJ stint for Chanel on Friday night. Preiss is due to release her first album later this month, then star in a play with screen heartthrob Gael García Bernal, before shooting a film with director Olivier Torres in January.
