Frankie Called Nick a 'Pancreas Boy'

Frankie Jonas Aka 'Bonus Jonas,' just 7 years old, made his MTV debut this week on TRL along with his brothers. Frankie revealed, 'I don't really know how I got the nickname. It just came up, and people started talking to me and going, 'Hey, Bonus Jonas,' and I was like, 'Hey, whatever.''

They boys love Frankie so much that even his jokes about Nick's diabetes amuse them. At a recent press conference, Nick said, 'Once I got comfortable with having diabetes, Frankie used to call me 'Pancreas Boy,' but he's the
cutest kid alive so he can get away with it.'

Frankie is hard to impress. Kevin said, 'He'll tell it straight up, and he'll be mean if he needs to.' Joe, 'He's a good critic. He's a mini Simon Cowell.'

Joe added that Frankie wants a big music career. 'He's always telling us that his band he's making.. he's always saying, 'You guys are going to open for me.' He's a funny little guy.'
