bruno mars cocaine GQ Bruno Mars is a slick dude. And just in case we forgot that, a new GQ magazine photo shoot shows off the 25-year-old singer in some top-notch outfits as Mars gives a primer on pulling off a fedora the right way.

In a quick interview with the magazine, Mars hits on typical showbiz platitudes, like "I keep it real," but he also seems genuinely psyched about his current success. "The last few months, it's been a rocket ... to Mars!" he says.

It hasn't all been smooth for the seven-time Grammy nominee, though. Although he wrote the hook to Cee Lo's 'F**k You' and has smoothly permeated pop culture, Mars faced a felony charge for cocaine possession in Las Vegas just last September.

"I'm not gonna preach that I'm a role model," he tells GQ. "I'm a f**king musician! But I've learned people are watching, so don't do nothing stupid."
