Katy Perry has said that she was scared to smoke marijuana with the rapper Snoop Dogg.

The 'California Gurls' singer, 25, collaborated with the hip hop legend on the track but said that she was worried about how strong his weed was, so instead she stuck to tobacco.

In an interview with Esquire, she said: "I was scared for my life to get off the hookah.

"Everyone else is smoking everything else. I was saying to myself, 'If that s**t still gets Snoop high, if I breathe it in I will die. I will be on a permanent balloon'. I was like, 'Hold on to the hookah'."
