It would be impossible for anyone to find out, unless they had good connections.
I understand that Nick is cute and all, but I'm sure it would kind of freak him out if some random fan just called him. Celebrities have to be careful about who they hand out personal info to, such a phone numbers. When your as popular as The Jonas Brothers, your already bothered by people way to much. I'm sure your intentions are very good, but it isn't a good idea.
P.S. Watch out for internet scams too. If you googled "nick jonas' phone number" I'm sure you'd get alot of results, and maybe some pretty promising advertisements. But, the truth is - it's all a scam.
