Blake Shelton isn’t shy about his drinking habits. (“I’m so drunk right now I just walked into a 7-11 put a bag of Skittles in my pants and shouted ‘Who wants to taste the rainbow?!!'” he once tweeted.) Nor the repercussions. (“I’m so hungover right now I just spent 15 minutes trying to DVR Growing Pains on my microwave,” reads another tweet.) So being that today (June 18th) is the country superstar’s 39th birthday, expect more side-splitting social media posts and a killer headache tomorrow. In honor of The Voice coach’s big, intoxicated day, we count down his best drinking songs.
