Legendary guitarist B.B. King, the recipient of more than a dozen Grammy Awards and an inductee of both the blues and the rock and roll halls of fame, was hospitalized over the weekend, according to a report.

A representative for the 89-year-old King of the Blues told TMZ.com on Monday that King remained hospitalized at a medical center near his home in Las Vegas.

Although the rep did not state the cause, King was diagnosed in 1990 with type 2 diabetes, and has been a spokesman for the LifeScan OneTouch Ultra blood glucose meter. He performed more than 70 concerts during a tour last year, but was forced to cancel an Oct. 3 show at Chicago's House of Blues and the tour's eight remaining shows when he felt ill and was diagnosed with dehydration and exhaustion.

As of Monday night, no updates had been posted on King's website.

King, whose countless awards include the Presidential Medal of Freedom, is the namesake behind the line of B.B. King Blues Club & Grill, which began in Memphis in 1991. Its Times Square club, the third, opened in 2000.

Last April, King was heckled at a concert at St. Louis' Peabody Opera House after he rambled, sometimes inaudibly, onstage, played a shaky song 45 minutes into the set, and continued to behave oddly through the show.

Days later, he apologized and his representative issued a statement saying that the diabetic King had "mistakenly missed a dose of his prescribed medication on the show day. The combination of the rigors of the very long drive [to the venue] and high blood sugar due to his medication error resulted in a performance that did not match Mr. King's usual standard of excellence."
