Having trouble differentiating your Nicks from your Joes? I know I’ve had that problem…well fortunately, we have Chelsea Staub to the rescue. As costar on the brothers’ popular Disney Channel sitcom “Jonas,” Chelsea spends a lot of time with the boys and knows them about as you well as you wish you could. So how does she tell them apart?

Chelsea described the brothers to Girl2Watch:

Nick is the youngest. He is 17, and he’s definitely the brains behind the band. He’s the little brother, but he’s in charge of it all and he writes pretty much all of the music. He definitely has “it”, whatever “it” is, Nick’s got it. He plays drums and keyboard and guitar and writes and does all of it well. So he’s definitely the musical one in that family.

Joe is the middle brother. And he’s just the entertainer. He’s a goofball on and off set.  He’s constantly pulling pranks and getting us into trouble and he’s great when he’s on stage. He really sells it.

Kevin is the oldest. He should be a salesman. He’s really easy to talk to, always dresses to the nines, and is definitely the manager of the band. He keeps everybody in check.

Okay, I was WAY off. I thought the oldest was Alvin.
