>> Marc Jacobs's longtime business partner Robert Duffy joined Twitter on January 29 — catch him while you can, he says he's only Twittering until Feb. 16 after the Marc by Marc Jacobs show.  In the week or so he's been on the social network, however, Duffy has shed a lot of light on upcoming projects at the company — as well as his business philosophy. For instance:

Duffy went to Los Angeles last week to work on an undisclosed movie project.

"Working on a movie project in LA. Also helping to edit a photo book about all the people that work with us. It's amazing! . . . The kids I work with all over the world are the most inspiring ever! So a book is being done on them. Working title 'the men and women of mj.'"

>> Devi Kroell and Lanvin Now Share an Investor —The Bartel family, founders of Travelzoo, who last November took a 12.5 percent stake in Lanvin's parent company, has been revealed as Devi Kroell's silent investor.  Bartel quietly took a stake in Kroell in 2008, allowing the designer to open boutiques and expand her product range; she's also holding her first runway show Feb. 15 during New York Fashion Week.  Bartel reportedly doesn't have the intention of building a fashion conglomerate, but has looked at investment opportunities in Christian Lacroix and Jil Sander in recent years.

>> Tyra Banks first approached Andre Leon Talley to be on America's Next Top Model eight years ago. “At that point," he told WWD, "I said no because it was the beginning. I was thinking I wanted to see where it goes.” Fast forward to 2010 and cycle 14 of the show, which premieres March 10 on The CW, with Talley on the judging panel:

I felt maybe I could contribute something to it that had not been on the show. I just felt that it was a way to step out of the box and associate myself with a very important American success story, a very important brand — Tyra Banks.

>> Burberry Fall 2010 to Be Streamed in 3-D —Avatar influenced the couture designs of Jean Paul Gaultier and Valentino a couple of weeks ago, but it was the technology — not the aesthetic — of the film which affected Christopher Bailey.  While the rest of London Fashion Week is being streamed in 2-D, Burberry will become the first brand to livestream its show in 3-D — to select guests in New York, Paris, Dubai, Los Angeles, and Tokyo, who will view the show in custom screening spaces designed by Bailey himself. For at-home viewers, the Feb. 23 show will also be projected in 2-D via live.burberry.com.
