So where will Mrs. S be when she graces us with her musical talent in episode nine? "Move your belt up a notch or two because we're going on a ride to England," the series executive producer Graeme Manson spilled to ETonline.

Manson confessed that he's always dreamed of having Kennedy sing on the series, but it had to be approached in just the right way, at just the right time. "Maria is a well-known musician with a number of albums and she's really great," he said. "It's something that's really close to her soul, but she had not performed [on screen] since [the 1991 film] The Commitments."

The showrunner continued, "She has not married the two -- film and her music -- since The Commitments, so I was very aware of that when I approached her with the idea."

Manson revealed that he was ready and willing to put a lot of the creative control into Kennedy's hands. "It was very much like 'Are you interested? Are you into the idea? What song would you like to do?'" he explained. "So it was very, very much we put it at her feet to see if she was into it."

Luckily, the former Tudors star was ready to showcase her amazing voice, and she picked a new original song to do. "She used a new song that she had. It might not have even been finished," Manson recalled.

"She came into the writers' room with her husband and music partner [Kieran Kennedy], and they played us a bunch of different songs. Her husband is in the band, by the way," he added. "So it was a very collaborative experience."
