Youngest Jonas Brother may join band

Teen popstars The Jonas Brothers have revealed that they are hoping to add one to their number.

Seven-year-old Frankie currently tours with brothers Kevin, 20, Joe, 18, and Nick, 15, and might one day be tempted to make the group a quartet.

Nick, 15, said: "It's the three of us [on tour], plus our mum, dad and our seven-year-old brother Frankie.

"We call him the Bonus Jonas, and he's awesome. One day, he might join the band."

The Disney Channel recently announced that it is to make a reality show about the group.
