Dogg, 42, whose real name is Calvin Cordozar Broadus Jr, said he once puffed on marijuana in the bathroom at the official residence of president Barack Obama in Washington DC, reported Contactmusic.
"(I've smoked) in the bathroom (of the White House). Not in the White House, but in the bathroom," he said on a TV chat show.
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.
"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 added.
