Naked Idol
The premise of Naked Idol is that The Naked Brothers Band have a Naked Idol contest for a new bassist replacing Rosalina (Allie DiMeco) and features a guest appearance by David Desrosiers (from the band Simple Plan).
Plot
Rosalina comes back after her Music Cruise. But Michel (the French guy Rosalina kissed on the cruise) also comes back, kisses her, and criticizes Nat's music causing Rosalina to break up with Nat and the band.
So Nat and the band go all around the country, searching for a new bass player and meets some of the greatest musicians that ever lived. The band picks a girl named Kristina who is a great bass player and is really nice, but Nat isn't over Rosalina so he comes off a little mean in the beginning.
Soon Nat realizes that he doesn't want to go through the breakup alone and they all have a group hug and sing at their house. Rosalina then tells Michel that she is too good for him and leaves to go over to the Wolff's house.
