The Webers prepare for their upcoming Christmas show, but things don't go to plan. The USA's biggest circus calls Kaleah and Kiarnna to book them as guest headliners and the girls head to LA.

Kaleah and Kiarnna arrive in Hollywood, hitting the sights before travelling to San Diego for rehearsal for their headline act at Circus Vargas.

In San Diego, Kaleah and Kiarnna continue rehearsals ahead of their debut, but a winch malfunction almost ends it all.

After Kaleah and Kiarnna receive a standing ovation on stage at the USA's largest circus, they travel to Las Vegas, and what happens in Vegas stays in Vegas.

Kaleah and Kiarnna round off their USA tour with a visit to New York, and the pair act like the world ended in Central Park when a pigeon poos on Kaleah.

With just one day to go until the Christmas spectacular opens, there's a chance that Kiarnna's debut show doesn't happen.
