It seems that the pop star Christina Aguilera has made a niche for herself in the musical television drama series 'Nashville' and she will return for another appearance in Season 4 Episode 19 of the ABC show titled 'The Storm Has Just Begun,' which will be aired on April 22.

According to Latin Post, the Grammy Award-winning musician made her first appearance in the musical drama in the episode titled 'Nobody Knows But Me' and portrays Jade St. John, a woman who earlier played a large role in the personal and professional lives of protagonist Jeff Fordham, portrayed by Oliver Hudson.

KdramaStars reported that the 34-year-old singer has signed on for a multi-episode arc, stating, "fans might wonder why the singer is not a series regular."

Apart from Aguilera, ABC has also confirmed several other guest stars for 'The Storm Has Just Begun.' According to the network, in 'Nashville' Season 3 Episode 19, fans will also see the 21-year-old actress and singer Aubrey Peeples portraying the character of Layla; Ed Amatrudo reviving his recurring character Glenn Goodman; Nashville native David Alford playing the role of Bucky Dawes; Broadway star Kyle Dean Massey appearing again as gay singer-songwriter Kevin Bicks; and Bostonian Nick Jandl portraying the character of Dr. Caleb Rand.

In the upcoming episode, fans will get to see the brightest stars of the Tennessee town rallying around Teddy Conrad, portrayed by Eric Close, as well as his music education initiative, "Note By Note." According to ABC, Juliette Barnes (Hayden Panettiere) "plans her return to the spotlight, and Layla finds herself thrust into it - alongside Jade St. John."

Elsewhere, Deacon Claybourne "receives the call he's been waiting for" - apparently a life-changing news." The synopsis reveals that Charles Esten, who plays Claybourne on 'Nashville,' is already aware of something regarding life-changing events. For instance, Look to the Stars revealed that his 15-year-old daughter, Addie, was diagnosed with leukemia at the age of two-and-a-half years, and since then, he has been actively involved in the Leukemia & Lymphoma Society.

'The Storm Has Just Begun' will air on Wednesday, April 22, at 10:00 pm ET on ABC.
