NEW YORK -- Garrison Keillor has asked Ulla Skaerved, his wife of six years, for a divorce, according to the New York Daily News.

"Garrison Keillor has just given his wife a one-way ticket to Lake Wobegon," columnist Richard Johnson wrote.

The paper reports that his new love, known only as Dorrit, hasung on Mr. Keillor's "American Radio Company of the Air" radio show and has been tutoring him in Danish, his wife's first language.

A spokesman for the American Public Radio network said Friday that Mr. Keillor had issued a "no comment" on the matter.

Mr. Keillor, 49, and Ms. Skaerved were married in Copenhagen, Denmark, in December 1985. It was the second marriage for both.
