Anne Hathaway is set to star in a musical in New York's famous Broadway theatre district.
The 'Rachel Getting Married' actress - who made her Broadway debut in 2002 show 'Carnival!' - has reportedly been having closed door reading with producers of new musical 'Promises, Promises'.
Theatre website Broadway World claims: "We have just got an exclusive account of a top secret, closed reading that happened over the weekend. Our guest, who was invited by one of the actors, reports that there was a full table reading and sing-through of the musical 'Promises, Promises' by Neil Simon, Burt Bacharach and Hal David.
"The reading starred Sean Hayes and Anne Hathaway along with a full cast plus several background singers, and was staged by director/choreographer Rob Ashford."
The show bosses are believed to have been overwhelmed by Anne's performance and excited by the chemistry between her and 'Will and Grace' star Sean.
The website added: "We're told that Hayes and Hathaway stunned the audience with their performances (both singing and acting) and that they garnered many huge and consistent laughs throughout - as well as a few tears."
'Promises, Promises' is a comedy based on Billy Wilder's 1960 movie 'The Apartment'.
It originally ran on Broadway from 1968 to 1972, with a total of 1,281 performances.
