According to the New York Post, the premiere party for “The Beautiful Life” is scheduled for this Saturday (September 12):

Club Tenjune’s owners are debuting their subterranean “SL” for Fashion Week, hosting parties for Rag & Bone on Friday and Saturday’s premiere party for the CW’s model-rific Mischa Barton’s vehicle, “The Beautiful Life.” (Simyone Lounge, 409 W. 14th St.; 646-289-3940)

New York Fashion Week also starts today and Nico might (but we are just speculating here) attend some of the shows with Sara if they can fit any in their busy schedule. I’m hoping to see the cast at the Zac Posen show on Monday September 14 (9:00 am at The Altman Building, 135 West 18th Street) since Zac guest starred in the pilot, but nothing has been confirmed yet.

Edit: We have been informed that Nico will be doing Lacoste, CK and a few more shows this weekend. Here are the details for the Lacoste and CK shows if anyone is interested:

Lacoste
Saturday September 12, 2009 at 10 am – Tent
Calvin Klein Collection
Thursday September 17, 2009 at 4pm 205 W 39th Street, Ground Floor

Hopefully a lot of photos will be released. We have also been informed that Nico’s brother Rocco (who, by the way,  is now on the set of “The Beautiful Life”) will be attending the premiere party with him.

Edit #2: According to On Location Vacation:

The Beautiful Life is filming on the corner of 48th and Broadway, at the Morgan Stanley building, NYC on September 14.

But I have no information if Nico will be on that set.
