'Austin & Ally' Season 4 Spoilers: No New Episode on Sunday; When will 'Duos & Deception' Air? [SNEAK PEAK]

Disney Channel sitcom "Austin & Ally", which is currently on its final season, will not be airing season 1 episode 6 as per the usual line-up, on 12 April. Instead, "Duos & Deception", will be aired on next Sunday, 19 April.

The tween-favourite show starring Ross Lynch as Austin Moon, Laura Marano as Ally Dawson and Raini Rodriguez and Calum Worthy as their sidekicks Trish and Dez respectively, has been on a hiatus since season 4 episode 5 "Homework & Hidden Talents" on 28 March. When "Austin & Ally" returns on 19 April, they will be bringing along couple of new singers too.

Trish has booked the sister-brother music duo Billie (Ryan McCartan) and Bobbie (Dove Cameron) of "The Billie Bobbie Show" to perform at the A&A Music Factory. However, their excessive adorableness and perkiness seem suspicious to Trish, who says, "There is no way that Billy and Bobbie are that perky".

Meanwhile, the voice-over warns, "Are they too cute? Is there something sinister behind those perfect smiles?" When a code inspector (rumours suggest the role has been taken up by Leslie David Baker) threatens to shut Austin and Ally's music school, the ulterior motives of Billie and Bobbie come to light.

Watch out for Season 4 episode 6 of "Austin & Ally" on Sunday, 19 April at 8.00 pm (EST) on Disney Channel.
