With holiday celebrations and preparations for 2012 occurring throughout the past week, stars were busy keeping fans up to date with their doings. Now that it's 2012, Brad Paisley couldn't help but humorously address the ancient Mayan omen that the world will supposedly end this year. Leave it to this guy to make apocalypse rumors funny! Additionally, Blake Shelton finished off 2011 with a bang, while Justin Moore could hardly keep his eyes opened on New Year's Eve -- we guess fatherhood will do that to you. Miranda Lambert did some deep cleaning to get ready for 2012, while Martina McBride celebrated the New Year at a family party. Finally, Kellie Pickler celebrated her one-year anniversary, while Wynonna Judd celebrated her engagement with an old-school photo of her and her fiancee.
