Nick, Joe and Kevin have admitted that after a long tour their hands are in bad shape, and that's when they go to get manicures. 

But don't worry; they don't paint their fingernails pink or red. Joe said in an interview, 'We don't paint our nails, but it could make a statement.' They also said that maybe painting their nails gold could be 'cool'. 

We don't know what you think about all this, but personally we like the idea of the Jonas Brothers with painted nails and think it would be pretty funny.
