Rapper Fat Joe has signed on to take charge of the urban and Latino division of Internet-based marketing company Market America just four months after his release from jail.

The Lean Back hitmaker, real name Joseph Cartagena, spent three months behind bars on tax evasion charges last year (13), and was released in November (13).

The 43 year old has also been tapped to host new MTV 2 show Off the Bat, which will centre on the lifestyles of professional baseball players.

He says, "It's not based on statistics and who has the most home runs. We want people to know that baseball players are people too. They're cool people."
