All of country music's biggest stars were in Nashville last night for the 43rd Annual Country Music Awards. Hosts Carrie Underwood and Brad Paisley were energetic and kept the crowd going. Carrie changed 10 times and performed during the awards show. The always gracious Taylor Swift couldn't believe she won Entertainer of the Year, and also performed along with Reba McEntire, Martina McBride and other country divas. It was definitely ladies night!
