Fashion Scoops: On The Croissette... Mother's Day...

The Ferretti/Chopard gown, meanwhile, is next headed to be auctioned at the amfAR gala, where it will be modeled by Eva Herzigova.

MOTHER'S DAY: Designer Rachel Roy and her hip-hop mogul husband, Damon Dash, have a new addition. Roy gave birth to the couple's second child, a girl, late Tuesday night in New York. Tallulah Ruth weighed in at 8 pounds and joins big sister Ava, 8.

MCQUEEN'S L.A. MOMENT: Alexander McQueen jetted in to Los Angeles for a one-night-only engagement at his new Melrose Avenue store. To be sure, it wasn't a typical store-opening party. There were hordes of people, yes, but in true McQueen fashion, the crowd ranged from Vidal and Ronnie Sassoon to Janet Jackson to Lisa Eisner. Most people — including Elizabeth Banks, Joy Bryant, Eve, Jamie Tisch, Elizabeth Callender, Anthony Kiedis and Tony Alva — only took a cursory glance at the ultramodern store, then headed out the back door to the parking lot, which was done up in a red-and-black Asian theme complete with hanging lanterns and mirrored pillars and bars. Jackson quietly took in the action at a round booth on risers in the back, dressed head to toe in red McQueen, and maintained a low profile. "His was the first fashion show I ever went to, more than 10 years ago, and it was just amazing," said Jackson, who is rehearsing for her upcoming tour. "Until now, we hadn't stayed in touch, but I love his clothes and think he's so talented."

McQueen then climbed up on a giant stage to introduce his "new friends," the punk-soul band The Gossip. "She's going to look fierce tonight," he said of the red sequin pantsuit he designed for curvaceous lead singer Beth Ditto. Apart from "people watching at the Chateau [Marmont]," McQueen didn't have time to do much else in L.A. "I've got collections to design," he said.
