Bonnie Brown, a former member of the Browns and a Country Music Hall of Fame member, is in critical care, and her family is asking for fans' prayers for her recovery.

A post on Jim Ed Brown‘s official Facebook page on Saturday (July 2) reveals that Bonnie Brown -- who is battling lung cancer and is Jim Ed Brown's younger sister -- "experienced complications from a blood clot" and is in a critical care unit.

"We hope you will all lift her up in prayer," the post concludes. "Thank you in advance.”

Bonnie Brown first revealed her cancer diagnosis in September; specifically, she has Stage IV Adenocarcinoma in her right lung. Her announcement came just slightly more than three months after Jim Ed Brown's death on June 11, at 81 years old, from lung cancer.

“As Jim Ed said at the announcement of our induction into the Country Music Hall of Fame earlier this year, ‘Cancer is no fun,' and I agree," Bonnie Brown said in September, adding, "I have full faith in my oncologist ... and I trust in them to determine the best path to my full recovery. I am surrounded by the love and support of my family, and I am determined to live many more years.”

Jim Ed Brown, Bonnie Brown and their sister Maxine Brown created the Browns in 1955. Hits such as “Here Today and Gone Tomorrow” and “I Take the Chance” led them to country music fame. They were inducted into the Grand Old Opry in 1963, but they disbanded in 1967, at which point Jim Ed Brown began his solo career. The trio joined the Country Music Hall of Fame in 2015.
