The Rose Bar at the Gramercy Park Hotel was--what are the kids saying nowadays?--"en fuego" on Saturday night. Not only was it downtown doyenne Stella Schnabel's 25th birthday party (hence Zac Posen, Arden Wohl, and Lola Schnabel's attendance), but "Gossip Girl" cast members Blake Lively and Chace Crawford, along with Michelle Trachtenberg, showed up for a few games of pool, too. And although he was often in the middle of a gaggle of girls, the much lusted-after Crawford had his eyes on one in particular: a certain supermodel that we won't mention. Not only do we want to build some suspense, but it wouldn't be fair to give the lucky lady's name—'cause she rejected him! Let the guessing begin.
