Stella's Last Weekend

The band's next concert stop is in New Orleans where Nat reunites with a childhood friend, sending Rosalina into a jealous frenzy! Meanwhile, Alex initiates an extreme environmental movement to help save polar bears at the North Pole, but devious reporters frame him to appear as a conceited rock star who hates Santa!

When Nat sees a tabloid photo of Rosalina kissing a young Frenchman during her "around the world cruise", he becomes convinced that he’s losing her for good and goes into a funk that threatens to prevent him from finishing the movie the band is making.

After making it to the top of the charts, members of the Silver Boulders, a popular tween rock band, find themselves undermined by internal squabbling as the bandmates seek different creative directions.

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.
