Is it the end of an era for YG and DJ Mustard? The West Coast duo’s relationship has taken a turn for the worse after the two sparred on social media.

Mustard is responsible for executive producing YG’s critically-acclaimed debut My Krazy Life including his hits “My Ni**a” and the Drake-assisted “Who Do You Love?”

But according to DJ Mustard, he has yet to be paid for his work. He told his Instagram followers to stop asking him about YG because he hasn’t seen any money off the project. “I still ain’t got paid [sic] for his album! So I don’t give a fuck!!!!” he said.

YG fired back in an expletive-laced post on Instagram, claiming he was never paid for shouting out Mustard’s tagline and his contributions to Mustard’s album 10 Summers.

“Wait what? DJ MUSTARD FUCK YOU NIGGA. FUCK EVERYBODY THATT AINT GOT PAID FOR MY ALBUM and DJ MUSTARD I KNOW WHERE YO STUDIO AT NIGGA. & THATS ME SAYIN ‘MUSTARD ON THE BEAT HOE.’ YOU AINT NEVER PAID ME FOR THATT OR YO ALBUM NIGGA.”

Mustard planned to meet up with YG to settle things face to face. “Say no mo I ain’t for no sucka shit and this internet shit weak we can get down this won’t be the first time,” he said. “I’m finna pull up we can squabble up !!! See yo in 30 killa.”

It was all good just a few weeks ago when Mustard was defending YG after his Grammy snub.
