A nixed collaboration may be to blame for Eminem and Snoop Dogg’s beef.

Daz Dillinger claims that the rappers’ recent feud stems from a feature that Eminem rejected years ago. During a Clubhouse chat with Royce Da 5’9″, N.O.R.E., and Joe Budden, Tha Dogg Pound rapper revealed that Snoop agreed to appear on “Bitch Please II” for Eminem’s 2000 album The Marshall Mathers LP. But when Snoop asked him to appear on his album, Em didn’t return the favor.

“When I was talking to Snoop, he said he asked Eminem to get on his album and they told him no… And Snoop felt some type of way,” Daz said. “I did all this and all that and they tell me no. Snoop was like, ‘Don’t nobody tell me no.'”

“He took it personally,” added Daz. “And from then on, that’s why you never heard a song from Snoop or Em since then.”

It was also noted that Eminem may not have even known that Snoop had requested the feature, and that his manager Paul Rosenberg could have been the one to turn it down.

Royce Da 5’9″ offered his own take on why Em came for Snoop on “Zeus.” “That energy that was coming off of Snoop in that interview, [whether] he meant no harm or not, I think he just looked at it like, it’s a more respectful brotherly way to say what you said,” said Royce, while admitting that Em took it too far. “But I agree though, it didn’t have to be a diss in a song behind that.”

Back in July, Snoop did an interview with “The Breakfast Club” and explained why Eminem was not deserving of a spot in his top 10 MCs, saying he could “live without” the Detroit rapper’s music.

The comments prompted Em to clap back on “Zeus” off his new project Music to Be Murdered By – Side B. “And diplomatic, ’cause I’m tryna be / Last thing I need is Snoop doggin’ me / Man, dog, you was like a damn God to me / Man, not really / I had dog backwards,” he raps.

Em opened up about Snoop’s “disrespectful” comments on a recent airing of his Shade 45 show. “I think it was more about the tone he was using that caught me off-guard ’cause I’m like, where is this coming from? I just saw you, what the f**k? It threw me for a loop,” he explained. “I probably could’ve gotten past the whole tone and everything, but it was the last statement where he said, ‘Far as music I can live without, I can live without that shit.’ Now you’re being disrespectful. It just caught me off-guard.”

But Snoop is not backing down. Commenting on a fan’s Instagram post, he slammed Em’s diss, writing, “Pray I don’t answer that soft ass Shit.”
