Now that Marie Osmond has settled into her role in The King And I, what better way to let America know she's the new Anna than on TV's Rosie O'Donnell Show? Osmond will appear with the children's ensemble Jan. 20, ABC-TV, 10 AM (ET), and sing "Getting To Know You."

O'Donnell's championing of the stage has made her show a haven for theatre guests and Broadway companies of such shows as Titanic, The Life and Grease!.

Osmond fills the hoop skirts that were worn by Donna Murphy (who originated the Anna role in the 1996 revival and received a Best Actress Tony Award for her performance) and Faith Prince, who completed her nine-month engagement as Mrs. Anna, Dec. 14.

Osmond is making her Broadway debut in The King and I but is in fact no stranger to the world of Rodgers & Hammerstein: She starred as Maria in the U.S. and Canadian national tour of The Sound of Music in 1994 and 1995, and reprised the role earlier this year in a tour across Southeast Asia.

She first won the hearts of the American public when she appeared with her singing brothers on TV's "Andy Williams' Show" in the '60s, and went on to star with her brother Donny on ABC's "The Donny and Marie Show." It was recently announced that Marie and Donny will be reunited on TV next year when they team up for a syndicated talk and variety show. The King and I, starring Murphy and Lou Diamond Phillips and directed by Christopher Renshaw, won a 1996 Tony Award for Best Revival. Kevin Gray now stars as the King of Siam. Tickets are available through Ticketmaster, (212) 307-4100.
