With the release of his new movie, Dead Man Running, rapper Curtis “50 Cent” Jackson is getting serious about acting, but admits he wants his next role to be a little more frothy.

“I want to play the lead in a romantic movie,” he tells the UK Mail on Sunday’s Live magazine. “Jessica Alba would be my perfect co-star — what man wouldn’t want to do a romantic movie with her?”

But when he’s not planning on whisking Jessica off her feet (on screen, of course), Fiddy is adding to his G-Unit business empire.

“The credit crunch has hit rap — I’ve even started trading in my old diamonds,” he says. “I buy diamonds on a very regular basis.

“I like jewelry but you have to go with the times and now I’m selling my old stuff before I get something new. These are times when we can learn about the value of money.”

All good advice. How can we learn 50 Cent’s other tips to reaching the top?

“I’ve written a manual for today’s businessman,” says the 34-year-old. “It’s called “The 50th Law.” In the board room you have to learn to be the top man.

“My tip is to not move, ever, in a business meeting. Don’t move, don’t speak, don’t nod. People will fear you and respect you.”
