Wynonna Judd reportedly suffered a medical emergency that led to the cancelation of her Saturday night (Sept. 30) concert.

TMZ reports that just before Judd was due to take the stage at Aura Nightclub in Portland, Maine, the singer's production manager informed the crowd that Judd had a "medical emergency" and would not be performing.

Someone called 911, but after the fire department arrived, Judd did not want to be taken to the hospital, so the EMTs left the scene, according to a law enforcement source. No details have been released about the nature of her medical issues.

Judd is currently on tour with her band Wynonna & the Big Noise, with dates scheduled through April of 2018. She recently released her first music video in nearly 15 years titled "Keeps Me Alive." "It’s being in a darkness that is so dark that your soul cries out to get relief. Because of where I’ve been and the hell I’ve been through and just the primal, guttural cry with which I have shed many a tear over children, death, divorce, being in the music business for 37 years as part of my journey,” she tells Rolling Stone Country about the song.

The country star's latest studio album, named after her band, dropped in early 2016 and features Jason Isbell on a track called "Things That I Lean On," in addition to a cut titled “Ain't No Thing” penned by Chris Stapleton. The project debuted at No. 14 on Billboard's Top Country Albums chart.
