The Jonas Brothers revealed their nicknames for each other, and they are:

• Kevin Jonas: K2
• Joe Jonas: Danger
• Nick Jonas: Mr. President

We’d like to know the story behind each of those nicknames, especially Nick’s.

The Jonas Brothers performed at the Kid’s Inaugural: We Are the Future concert in D.C. on Monday night. Obama girls Malia Obama and Sasha Obama got to go up onstage with their favorite performers.

The Jonas Brothers Wikipedia page was hacked today, but now it’s fixed. If ex Jonas girlfriends could hack, they’d probably post a much nastier message.

Joe Jonas, the other Jonas Brothers, and Jordin Sparks did a duet of her hit song No Air, from the Jonas Brothers Tennessee show on Sunday.

The Jonas Brothers performed in New York’s Time Square on New Year’s Eve. The Jonas Brothers were part of Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest 2009.

There were a lot of screaming teen girls there to see the boys, who performed more than one song. What a treat!
