Rumours of the couple's plans to wed first surfaced in September (15), when the video vixen showed off an 11-carat ring, worth $350,000 (£218,750), on social media app Snapchat. She simply captioned the shot, "Yes!", and later added, "When it's real, you just know."

Ross subsequently confirmed the marriage news, telling, "Me and Lira are so close that it wasn't even about a question (sic). When the time came, I put that (ring) on her hand and let her know, 'It's time to take it to the next level.' She's a rider. She's a young star. She's a genius, a great thinker. Even more important, she's a great person."

However, it appears the pair, which began dating earlier this year (15), has since parted ways.

According to, Ross and Mercer recently became embroiled in a huge argument, prompting the model to move out of the hip-hop star's Georgia mansion.

The couple has yet to comment on the reports, and Mercer has yet to remove her rock - she was still pictured wearing the ring in a selfie she posted on Instagram on Monday (02Nov15).

Mercer has long been a fan of Ross - in a 2102 tweet, she wrote: "Ima (sic) Marry Rick Ross My fat boy lol (laugh out loud)."

The news emerges days after Ross, real name William Leonard Roberts, was taken off house arrest related to an alleged assault on two workers at his Atlanta home. A judge lifted the order on Friday (30Oct15) and told Ross to stay away from his victim, and notify officials before leaving the state of Georgia.
