Khloe Kardashian Looks Out Of This World At T-Mobile's Galaxy S 2 Launch In NYC! (PHOTOS)

The West Side of NYC was jumping last night as Khloe Kardashian, The Black Keys, Ed Westwick, Chace Crawford and Emma Roberts celebrated the launch of T-Mobile's eagerly awaited Samsung Galaxy S11 and the HTC  Amaze smartphones.

Khloe looked great in a black pencil skirt and a black and yellow floral printed blouse from the Kardashian Kollection for Sears. 

Crawford and Westwick dressed down in denim, while Emma Roberts wore a knitted sweater dress.

Patrons at the party were feted with drinks and finger foods: mini cheese burgers, spring rolls, skewered grilled chicken, and free giveaways including ear buds, earrings, ties and sunglasses.

While waiting for the Black Keys to hit the stage, T-Mobile provided demonstrations on how to use the phones. GlobalGrind was even treated to speed tests on the Galaxy S2 and must say, it's quite impressive. We will publish our own tests in a few days.

In the meantime, check out Khloe and Co. in the gallery above!
