AceShowbiz - Derek Hough revealed that his wife Hayley Erbert has undergone emergency brain surgery. When coming clean with his spouse's health scare, the "Dancing with the Stars" judge assures fans that she is in "stable condition" now.

On Thursday, December 7, the 38-year-old wrote on Instagram, "At the end of last night's tour performance in Washington, D.C., my wife Hayley became disoriented and was taken to the hospital." He added, "She was diagnosed with a cranial hematoma from a burst blood vessel and required an emergency craniectomy. She is in stable condition."

"I want to thank the first responders and medical personnel who have cared for and continue to care for her," the professional dancer continued. "I ask for your prayers and positivity during this time."

According to Mayo Clinic, an intracranial hematoma is "a collection of blood within the skull. It's usually caused by a blood vessel that bursts in the brain." The cause of this condition can be trauma such as a car accident or fall.

Derek and Hayley tied the knot in Northern California in August. In October, Derek divulged that he's ready to have kids with Hayley. "Are we ready to do this thing?" he asked his wife about the prospect as she stood off-camera in his interview with Extra after saying he was "absolutely" ready to have children.

Derek also gushed about being a newlywed. "It's so crazy to say that word 'wife,' honestly, and I love it. Wait till you see the (wedding) video," he said. "We got it the other day… I'm just bawling… it was like, I'm feeling it, man. It was like an ugly cry in the corner in the foetal position because I just thought it was so beautiful."
