Actress Mary Martin, who starred in such musicals as "Peter Pan," "The Sound of Music" and "South Pacific," has been hospitalized for tests, a spokesman said Monday in Los Angeles.

Richard Grant, publicist for Martin's son, actor Larry Hagman, refused to say where the actress was hospitalized or the reason for the tests."Miss Martin has been in the hospital for tests. That is all I will confirm," Grant said. "In this case we just don't choose to give out information."

Martin became a star of New York theater with her 1938 appearance in the musical "Leave It to Me." She also played nurse Nellie Forbush in "South Pacific" and Maria in a Broadway version of "The Sound of Music."

She first played Peter Pan on Broadway in 1954.

Martin was seriously injured in a 1982 taxi-van collision that left her manager, Ben Washer, dead. Actress Janet Gaynor and her husband, producer Paul Gregory, were severely injured in the crash.
