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).
