Chace Crawford left his girlfriend Carrie Underwood behind in NYC to host a NYE party in Miami tonight. He'll be hanging out with Mandy Moore, Kristen Bell and Dax Shepard (but "don't say our names together to promote this thing"), Jeremy Piven and more at the Raleigh Hotel. Miami is always a hot spot this time of year and this time the adorable Gossip boy was giving the people of South Beach quite a hot eyeful hanging out with N'Syncer J.C. Chasez over the weekend. As 2007 winds down once and for all, we just want to wish all of you a happy and healthy new year! Thank you all for helping make 2007 so amazing here at PopSugar. Hope you have a fabulous fun and safe New Year's Eve!
