50 Cent continues to mercilessly troll Lala Kent's producer beau Randall ...

50 Cent is on the social media warpath.

The 43-year-old rapper has been embroiled in a feud with Vanderpump Rules' Lala Kent, 28, and her producer fiance Randall Emmett, 48, over an outstanding loan he made to Emmett.

The rapper was back on social media Sunday looking to embarrass Emmett with a series of posts after repeated warnings of retribution if he didn't pay back the loan, which 50 Cent said was at $1 million until Emmett paid him $250,000.

The In da Club rapper, whose real name is Curtis James Jackson III, made repeated references to Emmett's claims he was suffering heart attack symptoms in a text exchange he had previously posted to Instagram.

On Sunday, 50 Cent posted a meme of late Sanford and Son star Redd Foxx mimicking having a heart attack with text of Emmett's claim he was headed to the emergency room for a check-up.

'You should have gave me my money,' 50 Cent wrote, adding, 'What the f*** is really going on LOL.'

He subsequently posted a shot of Emmett standing in a medical facility with a number of devices strapped to his chest hooked into a monitor.

50 Cent - who previously demanded the producer make good on his debt by Monday - wrote, 'Your not gonna die before Monday @randallemmettfilms go ahead knock your self out. LOL.' 

He subsequently posted before and after shots of Emmett's Wikipedia page, which was apparently locked after people edited it to reflect the details of the dispute.

The row boiled to the surface Friday after 50 Cent took to Instagram with a clip of Kent, 28, from her Bravo show revealing to castmate Stassi Schroeder that after they made love for the first time, Emmett bought her a Range Rover. 

'I let him hit it the first time and we were inseparable; he would just send me, like, really expensive gifts,' Kent, who got engaged to Emmett last fall, said in the clip. 'The first night we banged, I got a car the next day. He was like, "Do you want a Range Rover?"'
