Pop singer, Bruno Mars covers the April issue of GQ magazine. Inside, the Locked Out of Heaven star reveals the hard work it takes to write your own songs saying, "You know how hard it is to write your own song? That s--t is hard, man. It's so hard to do. I don't ever want to come out with something safe and get away with it 'It sounds good!' It's got to be more than sounding good. It's that unexplainable high. Why I keep doing it. That feeling that you keep on chasing and chasing. Because it's nothing, man. It's taking the air and turning it into something. That's the feeling." Find out Bruno's retirement plans inside. Mars' determination and passion for music is definitely noticeable in his high energy performances. But watch as many of them as you can because sooner or later, he plans to retire, "On a beach, drinking out of a coconut, watching some kids running around in the sand, looking at the ocean...And then planning a reunion tour, overweight." Tattlers, do you think by the time Bruno Mars retires that Justin Timberlake will have stolen his entire look by then?
