It was a precarious week for many Jonas Brothers fans!

After a flurry of rumors that Kevin, the oldest member of the Jonas Brothers, was quitting the band to pursue a solo career catered to an older audience, the Brothers have let us know that it just isn’t true.

On their MySpace blog, the Brothers wrote: “There is a rumour that one of us is leaving the group. Not true. We love what we are doing and hope to do it together for a long time.” The letter was signed off by each of the Brothers.

The announcement that the brothers are here to stay– together– comes shortly after the Brothers received their first Grammy nod last Wednesday: a nomination for Best New Artist. The brothers see the nomination as a “huge honor.” The nomination signifies an enormous career shift for the Brothers since their self-titled album was released last year. What was the first thing they did after hearing the good news? They toasted with cider and called Mom, of course!

Despite their fame and the recent Grammy attention, in a recent interview, Kevin Jonas admitted to still having feelings of nervousness when he’s around a girl he likes. He still gets excited around attractive women and claims that his head just “moves too fast.” However, he says, he’s not under any pressure to be tough or macho, describing himself as a “protective guy.”

And the boys haven’t let fame cloud their priorities– they’re using their name now to fight for the good causes. The Brothers recently managed to raise more money than any other celebrity after receiving $450,000 in donations in an online auction at charityfolks.com. According to the AP, the website “arranged VIP tickets and meet-and-greets in exchange for donations to the band’s Change for the Children Foundation.”

Runners-up in the race to raise charity money include Morgan Freeman, Robin Quivers and the cast of “The Sopranos.”

On December 3, the boys were on hand for the lighting of the Christmas tree at the Rockefeller Center. They sang “Girl of my Dreams” at the traditional holiday event.

Other performances included Britney Spears, Beyonce, and Faith Hill.

And the holiday fun isn’t over yet! Word has just been released that the Brothers will be kicking off 2009 at Dick Clark’s Rockin’ New Years Eve ABC special. Other performers will include Natasha Bedingfield, Fall Out Boy, Jesse McCartney, Ne-Yo, Pussycat Dolls, Solange and Robin Thicke.

The New Year’s celebration begins Wednesday, Dec. 31, at 10 p.m. ET.

Thanksgiving Day!

The Jonas brothers hardly ever sit still, but this week they’ve been in the public eye even more than usual.

On Thanksgiving Day, the musicians were the halftime entertainment at the Seattle Seahawks and Dallas Cowboys football game. (Cowboys won, 34 – 9).

They weren’t only there to support the Cowboys, despite the fact that they, too, live in the Dallas area, nor were they trying to publicize a new single or practice their dance moves.

Instead, they were advocating the annual Red Kettle Campaign, during which the Salvation Army begins its holiday donation drive. The boys hope to draw attention to this cause, which is not unlike their own charity, the Change for the Children Foundation.

On Friday the boys gave a book-signing in a Manhattan Barnes & Noble. Fans began gathering on

Wednesday evening, despite the fact that the Jonas brothers would not be arriving until Friday afternoon. According to the Daily News, along with the usual autographs, tears and confessions of love, one young girl was sick all night with excitement, and another was trampled by the crowd. An ambulance was called.

The Jonas Brothers’ new book is titled Burning Up: On Tour with the Jonas Brothers. It aims to give fans a glimpse of “real life” on the road.

According to the introduction of the book, the boys are sharing their “favorite memories of being on the road.” They want to “open up our lives in a special way so that you can experience the excitement and fun we get to live each and every day.”

Earlier this month, the Brothers also appeared on Jimmy Kimmel Live, performed at the 2008 American Music Awards and won the T-Mobile Breakthrough Artist award.

What do the brothers have in store next? Well, for starters, they want to meet Kanye. Good luck, boys!
