Snoop Dogg upset Michael Jackson by blowing smoke into his dressing room.
The rapper has opened up about his friendship with the late music superstar - who was like "family" to him - however, Snoop also revealed he once got on the King Of Pop's bad side by smoking weed backstage when they were both at an event in Las Vegas.
During an interview on SiriusXM's 'Andy Cohen Live', Snoop explained: "Me and Mike was family. His family and my family love each other. We have a record that never came out together. We never had issues.
"Only issue me and Mike had was we was at, what was that thing? Ed Hardy, Christian Audigier. He had an event in Vegas where they have all the clothes and all of that, so he had performers.
"He had Michael Jackson perform, Snoop Dogg perform, but where he messed up, he put Michael Jackson dressing room right next to Snoop Dogg, so Snoop Dogg is there doing this [smoking a joint]."
Snoop went on to reveal he ended up blowing some of his smoke into Jackson's dressing room and the singer - who died in 2009 - wasn't happy about it.
He added: "They like: 'You know, Michael Jackson's dressing room is next door.' I'm like: 'No it ain't.' They like: 'Yeah, there', so I'm like: 'Hold on. Open the door' ... [I blew smoke in] ... He's right there looking at me ... He said: 'Snoop, don't do that'."
During the interview, host Cohen asked the hip-hop star about the track he recorded with Jackson and Snoop insisted he has now idea what happed to it.
Snoop said: "I gotta find out. It's a record that was done for some sort of, you know, he did records for the world.
"It was like some peaceful, a whole lot of artists on it record. He called me one night and it was crazy because the way his voice came through the phone, he was like: 'Snoop, it's Mike. I have this song I want you to get on'. I'm like: 'Man, anything you want, Mike. It ain't no problem. Talk to me.'
"Then, after we got past the song, he was like: 'My mom always said that you look like someone in my family. I think we're related'."
Snoop concluded by saying: "I kind of want to hear it [the lost song]."
