On Friday night, Gucci's Creative Director Frida Giannini and DJ-cum-designer Mark Ronson hosted a party to celebrate a lineup of new Gucci projects including an iPhone app, a limited edition Gucci Ronson sneaker collection and Gucci's pop-up shop dubbed the Icon-Temporary Flash Sneaker Store (which will remain open for two weeks in NYC before traveling to Miami, London and Tokyo).

Feting it all in the tiny raw white space (save for the red and green Gucci stripes on the walls, natch) was Claire Danes, Evan Rachel Wood, Mischa Barton and Mary J. Blige, who had just cut the ribbon on the Mary J. Blige Center for Women along with supporter Giannini in her hometown of Yonkers, New York, the day before.

"I believe it's the most important thing I've done in my life and my career," says Blige of the center that aims to support young women.

"There were women standing there who were ready to walk in, and it's all there because of the help of people like Frida Giannini and Jay-Z and all of my friends."

Blige also revealed that she was hopping in the studio with her producer friend Ronson the following day for a cut on her new album, Stronger, out in December.

"The song is crazy," she said excitedly, while her husband tried on one of the eighteen styles of colorful $530 Gucci Ronson sneakers.

To prep for his designing role, Ronson says he visited vintage shops in New York to get inspiration.

"I bought all of these tennis shoes and wrestling shoes from the 20s and 30s to see how they were designed," said the avid sneaker collector, who is also working on his next solo album, due out in May. "I wanted them to be something that I would wear and that I wanted to put my name on."

And while, overall, the crowd seemed to dig them ("Maybe I'll be lucky enough to score a pair tonight," said Danes, who explained that the walking required in NYC automatically makes all New Yorkers sneaker heads), Wood admitted to being a fan of more low-key, economical kicks.

"I'm a total Converse girl! I just got the Dark Side of the Moon Converse for my birthday," she said before dishing to StyleList and The Misshapes Greg Krelenstein about her Halloween costume plans for later this week.

"I had a whole Halloween costume ready, but then I had to dye my hair for work," she said, referencing her newly brunette coif. "I was going to be Kim from "Edward Scissorhands" and I had the white dress and the scissorhand and everything.

But now I'm going to be Liza Minnelli's character in "Cabaret." It'll be totally f***ing obvious, but whatever."
