US rapper 50 Cent has denied reports that claimed his long time associate and fellow rapper Eminem was starting to look like an M&M.

Speaking to MTV News, 50 Cent said that Eminem was “in great shape" and hadn't put on any excessive weight.

“He looks good. I seen him in Detroit. He's gonna look real good when you see him return,” the rapper said.

As previously reported, Eminem is expected to make his comeback in June at Nelson Mandela’s 90th birthday celebrations in London’s Hyde Park.

The rapper, who is also expected to release a new album this year, joins a line up which already includes Razorlight, Stevie Wonder, Annie Lennox and Queen.

Tickets for Nelson Mandela’s Birthday concert are available via ballot only.
