Blues legend B.B. King was rushed to the hospital this weekend due to an emergency related to his diabetes.

The 89-year old guitarist, who suffers from Type II diabetes, was taken to the ER to treat dehydration and remains at a medical center near his home in Las Vegas, TMZ reports.

The “My Guitar Sings The Blues” singer has been living with his non-insulin-dependent condition for two decades. Last year, he canceled all of his scheduled performances due to medical issues.

Best known for playing with his signature electric blues guitar named “Lucille,” the influential King was inducted into the Rock and Roll Hall of Fame in 1987.

He has 15 Grammy Awards and was given a Grammy Lifetime Achievement Award in 1987 and a Grammy Hall of Fame Award in 1998 for “The Thrill Is Gone,” a song known for its “qualitative or historical significance.”

MTV News is waiting for an official comment from King’s rep.
