Former First Lady Nancy Reagan was hospitalized in Santa Monica after falling at her Los Angeles home Sunday morning, according to her spokeswoman, Joanne Drake. The cause of the fall was unclear.
Reagan's doctor recommended hospitalization as a precaution, and she was admitted while awaiting the results of various tests, Drake said.
"She has not broken anything," Drake said. "We don't have anything beyond that."
Reagan, 86, was staying in the same room at St. John's Health Center where her husband, former President Reagan, recuperated from a hip fracture years ago.
Drake said Nancy Reagan was in good spirits and hoped to be released today.
Nancy Davis -- born Anne Frances Robbins -- and Ronald Reagan, both actors, married in 1952. She was his closest advisor during his two terms as governor and two as president. The author of the Just Say No anti-drug campaign, she began a foundation to combat the use of illegal drugs.
She spent years caring for her husband while he suffered from Alzheimer's disease until his death in 2004. She still works at the Ronald Reagan Presidential Library in Simi Valley.
