A bunch of stars proved that there's no reason to wait for New Year's Eve to get the party started in Miami last night. Casey Affleck joked around with his brother-in-law Joaquin Phoenix, who apparently sees no reason to shave now that he's retired from the film industry [1]. Diddy and Jamie Foxx were also on hand to join in the fun, while January Jones kept it a little more low-key cozying up her boyfriend. Many of the big holidays may have come and gone, but there are plenty more good times to be had as we all gear up to say goodbye to 2008.
