Blues legend B.B. King was rushed to a hospital in Las Vegas this weekend due to a "diabetes-related emergency," according to TMZ.

TMZ also reports that the hospitalization is due to dehydration caused by Type II diabetes, which King has lived with for two decades, and that King is currently hospitalized in a medical center near his Las Vegas home.

The 89-year-old singer and guitarist has been performing regularly since 1949 — in 2003, it was reported that King had given over 15,000 performances in his career at that point — but has been unable to remain consistent later in life. King was forced to cancel eight shows near the end of 2014 after he was unable to finish October 3 performance at the House of Blues in Chicago, due to dehydration and exhaustion.

In April 2014, King issued an apology following an erratic April 4 performance at the Peabody Opera House in St. Louis, Mo., during which he did not perform a song for over 45 minutes. "Mr King suffers from diabetes – and he mistakenly missed a dose of his prescribed medication on the show day," his rep said in a statement. "Simply put, it was a bad night for one of America's living blues legends and Mr. King apologizes and humbly asks for the understanding of his fans."

Here's to a speedy recovery for the living legend. While waiting for updates on his condition, watch King's 2010 Crossroads Guitar Festival performance of "The Thrill Is Gone," his highest-charting single in the U.S., which peaked at No. 15 in 1970.
