FANS of the heavy-hitting tween music act, the Jonas Brothers, will get to see a new side of Nick Jonas tonight.

The Disney Channel is devoting an entire episode of its reality series, “Jonas Brothers: Living the Dream,” to how 15-year-old Nick copes with his diabetes.

The show, which is generally much lighter in tone, is a behind-the-scenes look into the lives of the multi-platinum artists, brothers Kevin, Joe and Nick.

But on tonight’s episode (7:55 p.m. on Disney Channel), Nick will discuss his experience with diabetes and how he has learned to cope with it – especially when on tour.

The band has been riding a chart-topping money train this summer, starting with the Disney Channel’s original movie, “Camp Rock,” and are now selling out shows on their hugely popular nationwide concert tour.

Their new album, “A Little Bit Longer,” debuts next week.
