Fashion Scoops: DeJa Vu... Kisa Crisis... Bamford Babes...

BALENCIAGA HAS A BALL: The fact that it was a school night for many of the guests didn't dampen the buzz at a cocktail to mark the opening of Balenciaga's first London store on Mount Street Tuesday night. "I'm filming [the sixth Harry Potter film] at the moment, so I can't do anything during the day," lamented the ultrapetite Emma Watson, explaining her absence from London's front rows during fashion week. So she took it upon herself to make the most of her time in Balenciaga's Space Age wonderland of a store, whipping through pieces from the floral spring collection hanging on the rails. Guests including Charlotte Gainsbourg, Nicky Haslam, Pat McGrath and host Nicolas Ghesquière meandered through the labyrinthine store, sipping gin and tonics and Xhampagne to the sounds of the eerie, electronic music that's piped through the shop.

STELLA GOES SHOPPING: "So sorry I'm late — I'm sure you've got more important things to do," joked Stella McCartney to photographers and fans at the launch of the "The World of Stella" two-week promotional event at Selfridges, Wednesday. Dressed in head-to-toe black, she sported her trademark blazer turned up at the lapel, and killer heels. And, while McCartney may have oozed effortless chic, it was in spite of a grueling schedule. "I should be saying I'm getting a good night's sleep, but it's not true — I get no sleep," said the designer, who gave birth to her third child, Beckett, last month, and is currently working on her fall collection, which makes its debut in two weeks. "It's always nerve-wracking in the last 10 days leading up to the show, but I had a good fitting yesterday and I'm feeling happy about it," she quipped.

EDUN GETS DARK: It might have been the snowiest New York night so far, but that didn't stop U2 frontman Bono from joining his wife, designer Ali Hewson, at the fall presentation of Edun. Held at The Historic Desmond Tutu Center, models stood in a completely dark room, only lit by spotlights over their heads.

"The theme was night and darkness, which is why it's so dark in here," Hewson explained of the collection, which is now in its seventh season.
