Fashion week fun and fabulosity!

On Wednesday, Us Weekly welcomed dozens of big-time stars for cocktails, grub and dancing at Lavo, a brand-new hotspot in midtown Manhattan. The occasion? Our 2010 25 Most Stylish New Yorkers bash — hosted by the Queen of Hip Hop Soul and Most Stylish New Yorker 2010, Mary J. Blige.

Singer Blige — who's prepping for a massive fall tour — stunned outside on the black carpet in a chic Willow dress. "It's comfortable!" Blige, 39, told Us.

One of the night's honorees, sharp-dressed man Scott Disick, hit the party solo without girlfriend Kourtney Kardashian. Disick told Us about another style icon in the making: Mason, his 9-month-old son with Kardashian. "My son has numerous suits," Disick, 27, gushed. "He's quite a snazzy dresser! They fit him perfectly, and he looks great."

Beth Ostrosky Stern (wife to radio superstar Howard Stern) dished on catching the shows at NYC Fashion Week. "It's been great!" the 38-year-old, rocking a pair of Christian Louboutin shoes, told Us. "I've had a really good time. Marchesa was amazing today."

Tony and Emmy winner and Glee star Kristin Chenoweth, 42, told Us about prepping for fall. On her must-have shopping list: "a scarf!"

Another fashion-forward Manhattanite on hand: Bravo star, cookbook author and new mom Bethenny Frankel — who let loose with hubby Jason Hoppy inside Lavo. The couple took Blackberry pics of each other, and danced to old school hits like Salt 'n Pepa's "Push It" — Frankel, 39, stayed on the dance floor for over two hours!

Among the other honorees of the evening: legendary supermodel Iman, Katie Couric (in a Carmen Marc Valvo dress and Stuart Weitzman shoes), Rachael Ray, talk show diva Wendy Williams, reality star and fashion publicist Kelly Cutrone, The City's Olivia Palermo, producer Swizz Beatz, indie rock darlings Vampire Weekend and many more.
