Tim McGraw is coming clean on why he chose to get sober, as he graces this week’s People cover. Inside the mag, the singer reveals that from his point of view, he drank a lot and needed to stop. His three daughters had a lot to do with the singer’s newfound outlook on life. Tim said, “I didn’t feel I had any moral high ground with my kids in the long run.” He decided to trade in whiskey for weight training five years ago. His new routine includes, “getting up in the morning and taking the kids to school and going to the gym and spending a couple of hours there.” When it comes to his 16-year marriage to Faith Hill, Tim says, it can be summarized in two words… “Yes, ma’am.” Tim’s issue of People magazine will be available Friday (2/1).
