Lana Parrilla may have to warm up her vocal chords…

Once Upon a Time, starring the 39-year-old half-Puerto Rican actress, is reportedly preparing a musical episode, which is slated to premiere sometime in the spring. However, there’s no confirmation from ABC‘s spokesperson regarding the news, according to TVLine.

The musical episode has been considered by the producers of the fairy tale series for quite some time now. Back at 2015’s Comic-Con, series co-creator Eddy Kitsis said in an interview, “It would be great to do a musical episode, [but] I don’t even know where to begin.”

“We all sing,” Jennifer Morrison said in a statement back in 2011. “Josh Dallas, Ginny Goodwin, me.” The actress added, “I don’t know if Robert Carlyle sings. He probably does. I feel like we have a lot of musically inclined people in the cast. We’ll see.”

Once Upon a Time returns with the second half of season six starting on Sunday, March 5 at 8:00 pm ET on ABC.
