Conservative radio commentator Rush Limbaugh announced Friday that he and his wife, Marta, are divorcing.

The Limbaughs "mutually decided to end their marriage of 10 years" and have "separated pending an amicable resolution," according to a statement released by Limbaugh's publicist.

It was the third marriage for both Limbaugh, 53, and his 44-year-old wife, who were wed May 27, 1994 at the Virginia home of U.S. Supreme Court Justice Clarence Thomas, who officiated the ceremony.

The couple shared a $24 million oceanfront mansion in Palm Beach.

Spokesman Tony Knight said the divorce was a personal matter and declined further comment.

The past several months have been difficult for Limbaugh, who went into drug rehab for an addiction to prescription painkillers.

He is also under investigation for illegally "doctor shopping" to obtain the pills. No charges have been filed against him.
