As Radar reported, Malia, 18, skipped the Democratic National Convention in July 2016 to party it up with her friends at Lollapalooza in Chicago. Onlookers posted shocking videos of her twerking half-naked and shaking her butt all over social media, but only Radar has this bombshell video of her puffing away on what an eyewitness claims was a marijuana cigarette!
