50 Cent has dismissed reports his mentor Eminem is battling problems with his weight, insisting the Slim Shady star is "looking good."

The hitmaker was rumored to have piled on the pounds at the end of last year after taking a brief hiatus from his hip-hop career. One tabloid even claimed Eminem - real name Marshall Mathers III - was "starting to look like an M&M."

But 50, who is signed to Eminem's Shady Records, has laughed off the reports. He tells MTV.com, "Em is in shape right now. He looks good. I seen him in Detroit. He's gonna look real good when you see him return. He's in shape right now."

However, the star admits Eminem has been struggling with another health problem: "The last time I seen him we played basketball together. He had a knee injury, so we chilled for a little bit."
