Chace Crawford was among the beautiful faces at the U.S. launch party for the BlackBerry Tour Smartphone at Thompson LES Hotel in New York City last night (July 29).

Joining the Gossip Girl beauty at the paid public appearance event were the likes of Chloe Sevigny, Brooek Sheilds and The City actress Olivia Palermo.

Though Ed Westwick was nowhere to be seen, we can assure you that the former roommates are still best friends. Chace may have moved out recently, but the twosome insist they’re still on good terms and hanging out more than ever.

“Chace and Ed are best friends,” a source tells the National Enquirer. “That’s not going to change anytime soon. They’re hanging out even more, now that Chace has moved out.”

So why did Chace move out? Ed is a messy pig!

“The truth is,” the source adds, “they’re both total slobs. What happened is that Chace just wanted a place of his own with more privacy. Ed has become more serious with his girlfriend, Jessica Szohr, and Chace was feeling a bit like a third wheel.”
