Doug Supernaw is currently in the hospital after he was diagnosed with two “advanced” forms of cancer.

The country star’s team shared the devastating news in a statement on the 58-year-old singer’s Facebook page.

Doctors discovered Supernaw — known for his ’90s hits “I Don’t Call You Daddy” and “Not Enough Hours in the Night” — had both stage IV lung and bladder cancer after he initially sought treatment for a severe cough.

“After struggling with a prolonged cough, Doug was admitted to the hospital on January 25th, where it was determined he was suffering from pneumonia,” Supernaw’s team wrote on Saturday.

“Additional tests found fluid on his heart and lungs which put his heart in an A-Fib condition,” they explained, adding that further testing discovered a “suspicious mass in his right lung,” leading doctors to transfer Supernaw to another hospital in Houston.

“It was at this hospital that his medical team confirmed several masses in his lungs, lymph nodes, bones, and bladder,” they continued. “The official diagnoses as of now is advanced, stage four, lung and bladder cancer. At this time, Doug remains in the hospital, awaiting more testing, while determining a treatment path.”

His team went on to thank Supernaw’s doctors and medical staff, as well as his friends and fans, before asking for privacy amid the challenging time.

“We would like to thank Doug’s amazing medical team for working so diligently in both the care and treatment, of our beloved Doug,” they said. “We would also like thank both our friends, and amazing fan base for the so many heart-felt prayers during this difficult time.”

“We appreciate that you will continue to respect Doug and Doug’s family’s privacy during these trying times. We will continue to provide updates as necessary,” they finished.

Supernaw first broke onto the scene in the late ’80s-early ’90s, where he remained a familiar face on the country charts until the late ’90s.

After taking a hiatus for nearly 20 years, Supernaw recently returned to music with an album of his re-recorded greatest hits released in April 2017.

Many of the songs on Supernaw’s newest album include his top 40 hits of “I Don’t Call Him Daddy,” “Not Enough Hours In The Night,” “Reno,” “What’ll You Do About Me,” and “Red And Rio Grande.”
