Aly and AJ Michalka will struggle to find perfect harmony when the singing duo guest-stars on the March 7 episode of The Good Doctor.
TVLine can exclusively reveal that the siblings will play a fictitious sister act—err, former sister act, on the ABC medical drama. In the episode, titled “Yippee Ki-Yay,” Andrews tries to please Salen by taking on the high-profile case of a famous pop star who is determined to get her voice back — even if it means undergoing a high-risk procedure.
Goldbergs vet AJ will play Nelly, the aforementioned Patient of the Week who lost her voice due to injuries sustained in a car accident. She maintains a close (though slightly strained) relationship with older sister/onetime singing partner Lexi (iZombie‘s Aly), who has since gone on to superstardom.
