THE Jonas Brothers are about to get bigger – if that’s even possible.

Teen boy-band brothers Kevin, Joe and Nick Jonas will star as secret agents in an upcoming Disney Channel series called “J.O.N.A.S” (Junior Operatives Networking As Spies).

“We’re secret agents, and our cover is that we’re a band,” Joe Jonas says in the most recent issue of Details magazine.

The brothers are fresh off their tour with Miley Cyrus, on whose show, “Hannah Montana,” they’ve appeared frequently.

All Disney is saying at this point is that “J.O.N.A.S” will premiere later this year.

The brothers’ Disney Channel movie, “Camp Rock,” airs in June.
