Last Saturday night Brad Paisley Played Indy and his opening act was Blake Shelton and Saturday just happened to be Blake's 35th birthday. Having to work on your birthday is bad enough, but being away from your new wife on your first birthday as a married couple is probably worse. Blake was getting ready to sing Joan Jett's 'I Love Rock 'n' Roll' when the crowd went nuts because wife, Miranda Lambert had entered the stage from the side and sang the song much to Blake's surprise. Miranda then asked the crowd to help sing 'Happy Birthday' to her husband and the crowd was more than happy to oblige, see for yourself.
