The cast of Elf (well, some of them) reunited over the weekend and one of the highlights was seeing Buddy and Jovie sing their duet of Baby, It's Cold Outside. Zooey Deschanel who played Jovie posted the video on her Twitter feed and it was so sweet to see. Check out Will Ferrell as Buddy and Zooey doing their thing. They sound as good today as they did back when they made the movie. To find out about more highlights from the reunion, click here
