What do Cameron Diaz, Hilary Duff, Frankie Muniz and Orlando Jones all have in common? They’ve got production deals with MTV.

The music cable network, hoping to boost production of more series, has tapped the stars to put on their thinking caps and start creating. In the case of “Charlie’s Angels” star Diaz, the actress plans a travel series that she will star in and executive produce, says the Hollywood Reporter.

Her as-yet-untitled show will track her adventures with friends at various hot spots around the world, and she will address environmental issues specific to each destination, says the trade paper. One such location will be the Chilean desert, where Diaz, 31, reportedly has gone sand surfing.

The show will also reveal how Diaz and her pals rough it without indoor plumbing and other niceties — such as personal assistants.

As for the other projects, though details are sketchy (especially in the case of ex-“Lizzie McGuire” star Duff), Muniz, the star of FOX’s “Malcolm in the Middle,” will host a series featuring genuine high school students as they live out their fantasies.

Meanwhile, Jones (“Drumline”) will lend his voice to multiple characters in the animated series “Chico & Guapo,” about two janitors trying to break into the music biz at their place of employment, a New York hip-hop recording studio.

In other MTV news, the network says it has Sean “P. Diddy” Combs, Kid Rock and Nelly joining the already-announced Janet Jackson at the halftime show it is producing for Super Bowl XXXVIII on CBS Feb. 1.
