Lady Gaga praised marijuana as she lights up on stage
The 26-year-old singer told her fans she had cut down on drinking alcohol because she prefers smoking the drug and revealed it had been hugely beneficial to her music.
According to The Sun newspaper, she said: “I want you to know it has totally changed my life and I’ve really cut down on drinking. It has been a totally spiritual experience for me with my music.
“It’s like saying everybody needs to take a breath and it’s going to be OK.”
She also joked she was going to talk to US President Barack Obama in a bid to make marijuana legal in America.
The eccentric singer recently had a tattoo inked into her newly-shaved head in front of a live audience as part of the launch for her new perfume Fame.
Gaga had an image of a cherub wearing a crown etched into the back of her head at New York's Solomon R Guggenheim Museum and tattooist Mark Mahoney said the design is a nod to her Italian roots.
Mark, who was helped by his assistant Wes Brown, explained: "It's kind of a Renaissance era cherub, a nod to her Italian heritage."
The singer, whose real name is Stefani Germanotta, put on a number of live art installation features during the evening to launch the scent, which included the singer arriving at the venue inside a replica of her perfume bottle, inside which she was asleep on a bed.
