Jake Gyllenhaal at Smyth Tribecca hotel

"Let the holiday parties begin! Jake Gyllenhaal braved the snowy New York City weather for a guys' night out at the Smyth Tribeca hotel, where Justin Theroux, Mark Ronson and Scott Campbell were throwing a bash to benefit God's Love We Deliver, an HIV/AIDS charity. The single actor chatted the night away with Matt Dillon and they seemed like they were having a great time,
a source says. Ronson, meanwhile, provided the evening's soundtrack and guests like Josh Hartnett and Mary-Louise Parker danced the night away". Source: www.people.com
