Rebecca Romijn
Looks like Jerry O'Connell took on daddy duty tonight as his well-dressed wifey hits the Cynthia Rowley show. Seriously smoking, mama!
Jonathan Cheban, Kim & Kourtney Kardashian & Scott Disick
Kim's Spin Crowd star joins the extended Kardashian family at the Jill Stuart show—and keeps the shades on to be able to take in all of their glossy glamour.
Gavin & Kingston Rossdale
The kid's got impeccable taste, (we've said it a million times before), and now we know why—he soaking it all up at Fashion Week! Genius, little dude.
Mary-Kate & Ashley Olsen
Because if you're gonna be singing karaoke at Barneys for Fashion's Night Out who else do you want to be judging you but the Olsen twins?!
Victoria Beckham
Posh strikes a pose to promote Victoria Beckham Dresses. She must be doing something right because Demi Moore quickly tweeted, "...can't wait to wiggle into the your new creations!" Ka-ching!
Ashlee Simpson
Ash is crowned the nicest celeb at the BCBG Max Azria show. But we think she also deserves honors for this jeans and BCBG leather jacket combo.
Rachel Zoe
Wow. When R.Z. talked about changing her look she really meant it. The stylist ditches her fur vests and blousy tops for a sleeker look at the 6th Annual Fashion Award Benefit Luncheon.
Dania Ramirez
The actress attends the Edition by Georges Chakra Spring 2011
fashion show minus an entourage.
Anna Wintour, Karl Lagerfeld & Diane Kruger
Oh, to be a fly on the wall as the Vogue editor, the Chanel designer and the fashionable muse (and talented actress!) put their heads together at the 6th Annual Fashion Award Benefit Luncheon.
Olivia Palermo
Whitney Port's City nemesis poses for pics at Peter Som's show. Figures the women wouldn't attend anything together.
Jessica Stam & Jessica Szohr
Rag & Bone's front row fashionistas include the model and the Gossip Girl star—unfortunately, sans her style-loving man!
Ellen DeGeneres
The talk show host shocked everyone (including us!) by walking in the Richie Rich show. Turns out fashionistas backstage had to sign a waiver promising they wouldn't spoil the catwalk surprise.
Karl Lagerfeld & Blake Lively
Serena van der Woodsen, or at least her alter ego Blake, knows it's not all about the Upper East Side. The Gossip Girl star heads downtown to Soho to make nice with the Chanel designer.
Sarah Jessica Parker
Chanel fan Carrie Bradshaw SJP heads to the store's reopening party in Soho looking as glam as ever.
Christian Siriano & Maggie Grace
Project Runway's greatest success story continues his run with a well-regarded show at Fashion Week. Heidi and Tim must be so proud!
Heidi Klum
The supermodel returns to the catwalk she knows all too well to kick off the Project Runway fashion show.
Jessica Simpson, Nina Garcia & Michael Kors
Spoiler alert! Looks like sparkly Jess could be the guest judge on the Project Runway finale...
Alexis Bledel
You gotta look chic at Fashion Week, and this former Gilmore girl's got it nailed. Hot shoes, hon!
Jamie-Lynn Sigler
The erstwhile Meadow Soprano snags a front-row spot (natch) at the Project Runway show.
See what gets the stars oohing and aahing in our Fashion Week Twitpics gallery!
