George Jones was hospitalized last night in Nashville. But fret not -- the Country Music Hall of Famer was just going in for an annual, routine checkup yesterday, Jan. 5. According to his publicist, Kirt Webster, doctors required that he stay overnight to ensure everything was all right, and so that they could continue to monitor him.

"I just decided I didn't want to drive back to Franklin in this cold weather," Jones quips. "So I guess I'll just stay here tonight and go home tomorrow."

He is expected to be released some time today, Jan. 6.

Due to an undisclosed illness, the singer canceled a pair of concerts back in early December in Akron, Ohio and Wilkes-Barre, Pa. respectively.

Jones' latest album release, 'George Jones: The Great Lost Hits,' contains 34 tracks from his prime vocal years, 1965-1972, such as 'A Good Year for the Roses' and 'Walk Through This World With Me,' plus a re-recorded version of 'Where Grass Won't Grow' with Trisha Yearwood, Dolly Parton and Emmylou Harris. He can also be heard on Staind singer Aaron Lewis' record, 'Country Boy,' which you can listen to here.
