Don't let Justin Timberlake's suit and tie fool you. The pop prince - who turns 36 today - might not rock tie dye, but he still enjoys puffing on a joint. Or at least he did in 2011 when he opened up about his cannabis use. "The only thing pot does for me is it gets me to stop thinking," Timberlake told Playboy. "Sometimes I have a brain that needs to be turned off. Some people are just better high."

And in 2014, he celebrated legalization with fans while performing in Denver. “It smells legal in here tonight,” he said to the Pepsi Center crowd. “Yep, I can smell y’all coming from a mile away - it smells legal in here tonight.” 

However, his very best marijuana moment came a decade earlier. Unlike celebrities who smoke openly - we're looking at you, Snoop and Willie -- Timberlake is discreet about his cannabis use. But he did admit to being high during one flashpoint in his early career - his infamous appearance on the debut episode of MTV's Punk'd, when Ashton Kutcher's team of pranksters donned "Tax Enforcement Agency" outfits and pretended to repossess Timberlake's car, his guitar, his house, even his dogs.

Timberlake was in tears by the time Kutcher revealed that it was all a hoax. And JT later said he was choked up because of cannabis.

"I actually stopped smoking pot for nine to 10 months after ['Punk'd']," he said in the 2011 Playboy interview. "I was so stoned. If you ask my friends, if they’re honest they would probably say that’s the only way to get me as dizzy as I was."

Or is Justin trying to punk us with a bogus explanation? Check out the clip and decide for yourself if Timberlake looks a bit blazed.
