It's only been a few days, but Kim Kardashian has already taken over New York.

The reality star posed on the red carpet with husband Kris Humphries at their lavish welcoming party in the Big Apple on Wednesday night.

In typical form, Kim, 30, stunned in a curve-hugging, floor-length nude dress designed by Victoria Beckham. She styled her hair in glamorous side-swept waves and accessorized with dark nails and sparkly earrings. Humphries, 26, coordinated with his new wife in a brown pin-striped suit.

After celebrating at the over-the-top bash held at Capitale, NYC, the newlyweds headed to Southern Hospitality with  Kim's sisters Khloe and Kourtney plus pal Jonathan Cheban -- all to catch Justin Timberlake, 30, give a rare, surprise musical performance with FreeSol, a band signed to his record label, Tennman Records. (Timberlake announced the impromptu performance via Twitter.)
