The Jonas Brothers treated their friends to a $5,000 shopping spree in US clothing store American Eagle.

The band, comprising siblings Joe, Kevin and Nick, decided to celebrate their current chart success by their father Kevin and pals including their 'Camp Rock' co-star Demi Lovato to the store and let them have whatever they wanted.

While their friends perused the store, the brothers picked up some boxer shorts and T-shirts for themselves.

The brothers are not short of money, having recently spent a staggering $2.9 million on a new six-bedroom mansion in the Vaquero Club gated community in Dallas, Texas. The musical trio recently appeared on Forbes.com's Hollywood's Top-Earning Tweens list.

They secured fourth position in the poll, topped by 'Hannah Montana' star Miley Cyrus, after each banking $12 million in a year. Nick dated Miley for two years but is now said to be romantically involved with Disney TV star Selena Gomez.
