POPPING UP: Kristen Scott Thomas and Diane Von Furstenberg are among the luminaries expected to pop into the soiree tonight for the opening of “The Pop Years” exhibition at the Pompidou Center, which is being sponsored by Yves Saint Laurent and the Gucci Group. A good number of artists have confirmed their presence as well, including Peter Blake, James Rosenquist, David Bailey and William Klein. Visitors to the massive installation will get an eyeful — and an earful. Amid the groovy plastic furniture and landmark paintings in the all-white setting, visitors can poke their head into Walter Pichet’s space-age helmet with a built-in television, listen to the music played at Andy Warhol’s factory and activate an air-raid siren by opening the door of a Jean Tinguely fridge sculpture.

SURGE IN SERGE: It’s been 10 years since the death of France’s beloved bad-boy singer Serge Gainsbourg. And suddenly, his rough and romantic tunes are turning up at fashion shows, too. Emanuel Ungaro is planning to show his collection to a Gainsbourg soundtrack on Wednesday, and Comme des Garcons kicked off its show on Sunday to one of his most famous songs, “Je t’aime, moi non plus,” a duet with his widow, Jane Birkin. And lo and behold, Birkin was front-row at Louis Vuitton on Monday, appreciating all the tributes. “Serge was always avant-garde,” she said. “He would have been pleased to hear his music on the runway.”

PATRICK PUZZLE: Is LVMH Moet Hennessy Louis Vuitton preparing to add to its British stable? Patrick Cox’s presence at the Louis Vuitton show Monday will no doubt fuel speculation that the French group might take a stake in Cox’s footwear, accessories and clothing company. “We’re in discussions,” said a spokesman for Cox. “I can’t say more than that.” Ditto for Yves Carcelle, head of LVMH’s fashion and leather goods business. He said Cox has been a consultant for the group for years and “today, there is nothing more to it than that. Although it may not seem like it sometimes, friendships exist in this business.”
Certainly Vuitton designer Marc Jacobs has his share. Among the designers in his front row were Martine Sitbon, Pucci’s Julio Espada and Anna Sui, attending her first Paris runway shows in 10 years.

VOYAGE TO PARIS: Voyage, the upscale London-based men’s and women’s hippie brand, will open its first address outside of Britain, in Paris, in late July. It will be in partnership with Alain Adjadj, the Paris-based entrepreneur who operates some 20 designer boutiques, including Dolce & Gabbana on the Avenue Montaigne in France and in the U.K. To be located at 56 Avenue Montaigne, the two-story, 2,000-square-foot shop will take the place of the Calvin Klein men’s store, which is set to close later this month.
