Reynolds checked into Cedars Sinai in Los Angeles. Her representative Kevin Sasaki said the 80-year-old entertainer has been forced to cancel appearances and concert engagements for the next three months, all in accordance to doctor's orders.
The "Singin' in the Rain" and "Will & Grace" star is scheduled to appear in the Tournament of Roses Parade on New Year's Day. She is slated to join the "Follow the Stars, Adopt a Pet" float, which is sponsored by the Pet Care Foundation in Beverly Hills.
Reynolds recently auctioned off a majority of her Hollywood Motion Picture memorabilia and costume collection, which she had been collecting for the last 40 years.
