Katy Perry has revealed how Snoop Dogg's weed smoke filled the studio during recording sessions for their 'California Gurls' collaboration, resulting in everyone working on the track doing so while high.
The single was a No.1 hit for Perry and Snoop in 2010, and Perry has revealed how the Doggystyle hip-hop star recorded his rap under the influence - perhaps explaining his presence on the track in the first place.
"It was really cool. He came by the studio, played the song and rolled a 'J'," says Perry in an interview with The Sun newspaper. "Everybody was contact high. But he was super-cool and he's been around forever."

Perry clearly didn't mind being high as a kite in the studio with Snoop, praising his attitude during their sessions together, adding: "It's really amazing if you meet someone that's been around for 20 to 25 years and they're still cool, because sometimes they aren't."
