50 Cent thinks Jay-Z is to old

50 Cent thinks Jay-Z is too old to continue touring.

The 'Candy Shop' rapper believes the hip-hop mogul signed his recent deal with Live Nation - which sees the company handle all of his records, touring, merchandising and marketing - because he is at an age where he doesn't feel he needs to continue negotiating different aspects of his professional life.

50 - real name Curtis Jackson - explained: "Jay is in a different space in his career. He may be tired of running around and negotiating each individual deal. The deal would be actually putting that in someone else's hands.

"I'm comfortable doing it the way I've been doing it. The difference between him and me is obvious.

"He's married to Beyonce, he's getting ready to be 40 years old. He's in a different place, he might not want to run around, and even touring may soon be out of the question. He might want to be in the office and run one of the companies."

50 also claimed another hip-hop star, 'Missing You' singer P. Diddy, has not released a good song for years - but says he is still one of the leading lights of rap music.

He added to KING-mag.com: "Puffy has the best model for staying relevant, because he does it without a song. He's been able to maintain an interest and stay in a space to executive produce television and film projects, andm stay relevant to hip-hop culture.

"What was the last record that made you feel like, 'Oh, my God, Puffy is on fire?' You don't need it."
