'Liv and Maddie: Cali Style' Premieres Tonight! Watch The New Opening Credits Now!

Not even Parker (Tenzing Norgay Trainor) knows how to explain what just happened in his new science class in this still from the season premiere of Liv and Maddie: Cali Style.

In “Sorta Sisters-A-Rooney”, Liv, Maddie (both Dove Cameron) and the rest of the Rooney family are excited to start their new life in California. As the school year begins, the Rooney’s cousin, Ruby (Lauren Lindsey Donzis), returns home from a summer trip.

Excited to have “sort of” siblings, Ruby can’t wait to finally be a sister but finds herself in the middle of a sister-fight between Liv and Maddie.

Meanwhile, Joey (Joey Bragg) and Parker attend their new science and technology school and their experience is not what they expected.

Liv and Maddie: Cali Style premieres TONIGHT, Friday, September 23rd @ 8PM ET/PT on Disney Channel.
