Teddi Mellencamp, star of Real Housewives of Beverly Hills, had been experiencing “severe and debilitating” headaches and was later hospitalized for “unbearable” discomfort.

The TV personality, who was part of the reality show for three seasons, revealed that following the doctor’s visit, they discovered she had multiple tumors in her brain.

“Yesterday the pain was unbearable and required hospitalization,” Mellencamp wrote on her Instagram page Wednesday. “After a CT scan and MRI, doctors found multiple tumours on my brain, which they believe have been growing for at least six months.”

She informed her followers that doctors would surgically remove two of the tumors that day, February 12. The rest of the tumors, the smaller ones, will “be dealt with via radiation at a later date.”
