Snoop Dogg smoked cannabis at the White House.

The 42-year-old rapper - whose real name is Calvin Cordozar Broadus Jr. - admits he once puffed on marijuana in the bathroom at the official residence of president Barack Obama in Washington D.C.

Speaking on the latest episode of 'Snoop Dogg's GGN News', he told Jimmy Kimmel: ''[I've smoked] in the bathroom [of the White House]. Not in the White House, but in the bathroom.''

The 'Young, Wild and Free' hitmaker tricked security into thinking he was going to the toilet and he even managed to persuade them to let him light a napkin.

He explained: ''I said [to the security guards], 'May I use the bathroom for a second?' And they said, 'What are you gonna do, number one or number two?' I said, 'Number two.' So I said, 'Look, when I do the Number two, I usually, you know, have a cigarette or light something to get the aroma right.'

''And they said, 'Well you know what? You can light a piece of napkin.' I said, 'I'll do that.'

He then inhaled his cigarette and added: ''And the napkin was this.''
