Country music star Loretta Lynn, who suffered a stroke recently, has moved from a hospital to a rehabilitation centre, her representatives said on Monday.
Reuters reported that the 85-year-old had been admitted to a Nashville hospital on May 5.
Her upcoming shows have been postponed on her doctors' advice while she recovers, a statement on her website said earlier this month.
Lynn, one of the first women to attain country music stardom as both a writer and a performer, had shows scheduled across the United States through November.
The Grammy winner first made waves in the 1960s with the autobiographical song Coal Miner's Daughter, which was turned into a best-selling book and a 1980 movie starring Sissy Spacek as Lynn.
Meanwhile, another veteran singer, Olivia Newton-John, 68, has also been forced to cancel her shows because of sciatica.
The ailment leads to intense pain in the lower back and legs that is caused by pressure on the sciatic nerve.
Her concerts scheduled for this month will be postponed, a statement on the pop singer's Facebook page said.
Also a Grammy winner, Newton-John, who first found success in the 1970s and performed in Singapore in May last year, overcame breast cancer in 1992.
