Laura Marano & Ross Lynch: New 'Austin & Ally' with Chloe & Halle Bailey!

Laura Marano sparkles next to Ross Lynch in this exclusive still from Austin & Ally.

In “Moon Week & Mentors”, Austin (Lynch) and Ally (Marano) are asked to be celebrity judges on a singing competition show that is celebrating “Austin Moon Week.” Ally takes a contestant under her wing that reminds her of her former, shy self and she and Austin work to make the girl a top contender.

Meanwhile, Trish (Raini Rodriguez) and Dez (Calum Worthy) try and create the most impressive fan signs in an effort to be seen on TV.

Guest star Halle Bailey told JJJ, “Working with Ross and Laura was wonderful. We met them during our “N.B.T.” (Next Big Thing) season, where they mentored us during the first round of competition. Since then, we would always bump into each other and became good friends. Being able to work with them was like hanging out with your friends all day. It didn’t even feel like work! Just a bunch of kids having fun and shooting an episode.”

“Moon Week & Mentors” airs Sunday, September 15th @8:30PM ET/PT on Disney Channel.
