Celebs go commando! From Jennifer Lawrence to Reese Witherspoon, many stars have taken the bold (but sometimes regrettable) choice to ditch their undergarments.
Ditching underwear, the Mad Men actor showed off his ahem, package, while shopping in N.Y.C. September 2012. He later vented about the incident to Rolling Stone, saying, "They're called 'privates' for a reason. I'm wearing pants, for f--k's sake. Lay off. I mean, it's not like I'm a f--king lead miner. There are harder jobs in the world. But when people feel the freedom to create Tumblr accounts about my c--k, I feel like that wasn't part of the deal…but whatever."
