Kristina Reyes
Rosalina comes back after her music cruise, but Michel (the French guy Rosalina kissed on the cruise) also comes back, criticizes Nat's music, and kisses Rosalina which Nat sees. This causes a heated fight between Nat and Rosalina in which they break up and Rosalina quits the band.
Everything is finally finished for the premiere of The Naked Brothers Band "Musical Mystery Movie". Now the band has to go through the press release and the red carpet! Nat, hearing about Rosalina wanting to be back in the band, has to decide, along with the rest of the band, whether to keep their new bass player, Kristina, or agree to let Rosalina back in the band. The director that Cooper replaced is still out to get revenge on the Naked Brothers band for firing him as a director.
