Marie Osmond has been in hospital following a bad reaction to medication, a spokeswoman has said, denying reports that the singer attempted suicide.
Marie Osmond enjoyed success in the 1970s with brother Donny
Publicist Amy Hawkes said the 1970s star spent a few days in hospital after the incident but was now "doing fine".
She told the Associated Press: "She's vacationing with her family right now."
US magazine National Enquirer reported that Osmond was in hospital as a result of a failed suicide attempt.
Marie Osmond's manager Karl Engemann said: "We deal with those tabloids all the time. You get tired of responding. It's like punching Jell-O."
The singer spent a few days recovering at Timpanogos Regional Medical Center in Utah, Ms Hawkes said.
"She basically had an adverse reaction to some medication she was taking and she blacked out," she added.
The manager would not confirm what type of medication Osmond was taking.
In 1999, the singer revealed she suffered from severe postpartum depression after the birth of her son.
Osmond found fame in the 1970s when she appeared alongside her brothers at several concerts before releasing her own single Paper Roses in 1973.
It became the first number one for a female on the country charts and her success grew when she joined her brother for the 1976 variety show Donny and Marie.
After years of TV work, she returned to country music in the mid-1980s but last charted in 1990 with the single Like a Hurricane.
She currently has her own company selling porcelain dolls, inspired by the dolls she collected when the Osmonds went on tour.
