The Hustlin' star popped the question to Mercer in September (15) with an 11-carat ring, worth $350,000 (£218,750), but reports of a romance-ending fight hit the Internet on Tuesday (03Nov15), with sources telling the model had moved out of the hip-hop star's Georgia mansion.

Following the reports, Mercer was pictured still wearing her ring and she has now responded to the break-up rumours. She is also firing back at allegations suggesting she cheated on Ross with fellow rapper Wiz Khalifa.

"I NEVER even met Wiz Khalifa EVER," she fumes on Twitter. "(Wiz's ex-wife) Amber (Rose) is 1 of my best friends & Ross has my (heart). Please stop with the fake stories & let me B happy Thx (thanks) smh (shake my head)."

Ross has yet to comment on the reports.
