Nashville fans can get a new glimpse of Steven Tyler's guest appearance.

Juliette & Avery Have 'A Lot To Overcome' On 'Nashville'

On Tuesday, a sneak peek was released where the Aerosmith rocker is backstage of a concert and gets ready to meet Juliette. Apparently, this is a big deal for her and Tyler seems pretty enthusiastic to work alongside the country icon. He even says her new single is "over the moon."

He also has his own single coming out that has potential to be an "H-I-T."

Teddy Will Reportedly No Longer Be A Series Regular On 'Nashville'

As he's escorted off, Rayna shows up where she gives insight on how Juliette's been doing lately. While others claim she's doing well, Rayna says that she spoke to her on the phone- and whatever is going on, it sounds dangerous.

Considering that Juliette's husband took off with their newborn daughter, the singer would not be in the most stable position. Rayna makes it clear that she's worried for her, but with Juliette's attachment to fame, there's a good chance that she's throwing her personal issues aside to focus on her work.

Another big storyline that fans can expect this season is what happened to Deacon during his operation. There was a flatline, but it's unclear if that was for him or not. Even if his heart did go out, perhaps he could be revived back. After all, it might be difficult to continue the series without him, but viewers will have to wait and see.

Check out the sneak peek below.

Nashville Season 4 premieres on Wednesday, September 23 at 10 p.m. ET on ABC.
