You know you can count on Lady Gaga to set tongues wagging. This video shows the pop star lighting up a marijuana cigarette in front of thousands of fans during her concert stop in Amsterdam Sept. 17. The singer asked if anyone in the audience had weed before fans began throwing stuff on stage and Lady Gaga sniffed away until she found what she was looking for. Lady Gaga debuting her light-up wig was featured as a RightThisMinute Daily Huh? video.
