Last night's 6th Annual New Yorkers For Children Spring Dinner Dance (phew, long title!) was all about fashionable twosomes. Flame-haired Coco Rocha (a dye job from a few months back) accompanied Zac Posen to the event. They matched well with Coco wearing a black-and-white geometric floor-length gown from Posen's spring '09 collection. Meanwhile, too-cute-for-words couple Diane Kruger and Joshua Jackson were undoubtedly the best dressed pair on the night. Diane dazzled in a beautifully-created baby pink feathered Marchesa fall '09 dress, Alexander McQueen silver clutch and Fendi peep-toes. Is it just me or do they get better looking by the second?

Speaking of twosomes, showing off her new beau for the first time was Cat Deeley. The British TV presenter, who is now based in California, hit the red carpet with Jack Huston, an actor who once dated Helena Christensen. He is also the grandson of director John Huston, and is the nephew of Anjelica and Danny Huston. Cat wowed in a gorgeous white strapless silk fan gown designed by Alberta Ferretti.

Other guests to attend the charity event included Josh Hartnett, Rachel Zoe, Emmy Rossum, Olivia Palermo, and Hilary Rhoda.
