>> Frida Gustavsson Ends Irina Kulikova's Three Year Stint as Face of Marc Jacobs Daisy —She already appears in the Fall 2010 Marc Jacobs collection ads with Monica Jagaciak and Ann Kenny, but now Frida Gustavsson has another tear sheet from Jacobs to add to her pile. The 17-year-old Swedish model is the new face of Marc Jacobs Daisy, with an ad debuting this Fall.  Gustavsson replaces Irina Kulikova, who was the original (and so far, only) face of the perfume, which marked its third anniversary this year.  But though Marc Jacobs and his creative teamed swapped out their model, they're keeping one thing consistent: As usual, Juergen Teller is the campaign photographer.

>> She may be most known for a set of scandal-inducing cell phone photos, or for her starring role in the Diane von Furstenberg campaign for the second season running, but now Ali Kay — fiancee of Diane's son Alexander von Furstenberg — appears to be courting the fashion press.

She's holding her first fashion show, for her loungewear line Keep Me, on Wednesday, September 15 during New York Fashion Week.  The event will be held at the downtown nightclub Capitale (the former site of Baby Phat's fashion shows).  And the Miami native isn't going it alone: Her collection will share the runway with Prince Peter and Mick Rock's t-shirt collaboration, and Jamison Ernest's downtown streetwear line Yellow Fever, which often features contributions from friends like Theodora Richards and Vincent Gallo.  But with Kay's collection on the runway, a DVF sighting wouldn't be out of the question.

>> Britney Spears to Perform at Dasha Zhukova's Pop Party? —Gwen Stefani and Victoria Beckham have already RSVPed yes to Dasha Zhukova's Pop bash Friday night at the newly-revamped dive Don Hill's in New York, but neither is set to perform. Instead, the New York Times hints that there will be a "legendary guest entertainer with a notorious lust for life," and The Daily hedges a guess that it will be none other than Britney Spears, Pop's current cover girl: "Nothing's confirmed, we're told, but . . . The Daily hears whispers that the former pop princess is maybe/possibly/hopefully slated to take the stage." [NY Times, DFR]

>> The Going Rate for Celebrities at Fashion Week This Season? Up to $75,000 —Halle Berry is joining Rag & Bone for Fashion's Night Out and Diane Kruger is supposedly going to be at Chanel, but what kind of fee is being incurred for those kinds of celebrity appearances this season? Apparently, for shows, the sweet spot is between $30,000 to $50,000. Bold-faced names are asking for $75,000 just to show up for FNO, and some are trying to wrangle an advertising campaign as part of the package. Even Tavi Gevinson is reportedly commanding fees for her cameos (she's blogging for Barneys during FNO and styling for Alice + Olivia). [WWD]

>> Milk Studios provides many things during New York Fashion Week: show venues, after-party spaces, and even tiny cups of cappucino for makeup artists, hairstylists, and models backstage.

But for the past two seasons, the home to Proenza Schouler and Joseph Altuzarra's catwalks has been missing something crucial: cell phone reception.

Fortunately, that changes — starting today.  A source at Milk says the space is now armed with signal boosters and a wireless network for fashion show attendees, allowing editors and bloggers the chance to liveblog from the shows, check in with their offices, and catch up on Twitter if a designer's running late.
