Lady Gaga smoked weed on stage in Amsterdam, Holland on September 17, during a stop on her Born This Way Ball tour.
The pop star sat at the front of the stage and asked the crowd if they were "having fun." She went to pull out a cigarette, but opted instead for a rolled marijuana joint which had been thrown on stage.
After lighting it and taking a few puffs, Gaga threw the joint into the crowd and joked, "For those of you who are wondering if I'm high right now, I am not. That is not nearly enough to get me high." Watch a video of the incident here.
It is legal to smoke marijuana in Holland and fans littered Lady Gaga's stage with a slew of marijuana-related gifts, including a drawing of Gaga in front of a marijuana leaf, a T-shirt with marijuana leaves over the bust and another one which read "Mary Jane."
"I want you to know it has totally changed my life and I've really cut down on drinking," Gaga went on to say, during her performance. "It has been a totally spiritual experience for me with my music."
Following her stop in Amsterdam, Lady Gaga went on to perform in Paris, Germany, Switzerland, Belgium, Italy, Southern France and Spain.
Earlier in the month, Gaga hosted a launch event for the release of her fragrance "Fame," which she described as "slutty," at New York's Guggenheim Museum on September 13.
Gaga also recently revealed the name of her upcoming album, which will be called "ARTPOP." No release date has been announced.
