Emergency responders called to Wynonna Judd Portland show

The celebrity news site stated that they have reached out to Wynonna Judd's representatives for comment on the Wynonna's health, but they have yet to respond on the matter. Judd is currently in the United States with her band Wynonna & the Big Noise. The tour is scheduled to run through April of 2018. The singer recently released her new music video, "Keeps Me Alive."

The video is Wynonna's first in 15 years and according to Judd describes the ups and downs throughout her life both personal and professional.

During a recent interview, Judd described her new music and tour as a release for the darkness she has experienced throughout her journey in life.

Wynonna's most recent studio album was released in 2016. The current tour is Judd's comeback following a successful run in the 1990s. The tour has garnered positive reviews thus far.

Judd first made country music headlines as a duo act in the early 80s with her mother Naomi Judd in The Judds. They released seven albums with 26 singles, which include "Mama He's Crazy," "Grandpa" and "Why Not Me." to name a few.

The mother/daughter duo decided to go their separate ways professionally in 1991. Wynonna has since released eight solo albums with three of the eight reaching platinum status.Throughout Judd's career besides her professional success in the music industry, her personal life has also been a major topic of interest for her fans.

In 2003, Judd came out publicly on Oprah revealing her battle with an addiction to food. She admitted to being severely addicted to food using it as a coping mechanism to deal with relationship issues within her family. She later appeared again after shedding some of the weight revealing she had reconciled with estranged family members.

In 2012 Wynonna and husband Cactus Moser were involved in a tragic motorcycle accident in South Dakota which resulted in Moser losing his left leg. Judd spent several months supporting her husband as he recovered from the accident before returning to her career in music. It is hoped Judd's recent medical emergency is a nonlife-threatening issue. It would be very sad to see a setback for the singer just as she appears to have her life and career back on the positive and fast track once again.
