On the official website for Archbishop Mitty High School, Stock's alma mater, the school has posted this congratulatory message: "Congratulations to alumna Chelsea Stock '03 who will be starring as Ariel in the Broadway Disney musical The Little Mermaid. Chelsea made her Broadway debut in January of 2008 as a member of the chorus and has been the understudy for Ariel. While she has had stage time as Ariel, she will be going on regularly as the title role starting June 2nd."

A Disney spokesperson could not confirm the casting.

The Little Mermaid marks Chelsea Morgan Stock's Broadway debut. The actress has appeared in regional productions of A Year With Frog and Toad and Kiss Me, Kate. She received her BFA from the Boston Conservatory.

The Mermaid cast currently boasts Tony winner Faith Prince as Ursula.

"In a magical kingdom beneath the sea," according to Mermaid production notes, "a beautiful young mermaid named Ariel longs to leave her ocean home to live in the world above. But first, she'll have to defy her father — the king of the sea — escape the clutches of an evil sea witch and convince a prince that she's the girl with the perfect voice." The musical is based on both the Disney animated film (written and directed by John Musker & Ron Clements) and the classic Hans Christian Andersen fairy tale. The Little Mermaid features songs penned by Alan Menken and the late Howard Ashman for the Disney film ("Part of Your World," "Under the Sea," "Kiss the Girl," among others) as well as ten new tunes by Menken and Glenn Slater. Doug Wright (I Am My Own Wife, Grey Gardens) wrote the book.
