The Battleship star told People that she has not got any experience on stage but would like to give it a go.
"I've never done any theater, but I am trying to read for a few plays and hopefully I will get something by the end of this year in New York," she said. "I might as well dive in head first."
However, Decker admitted that she is perhaps not suited to a musical as she cannot sing or dance.
"I am no triple threat," she said. "Not even a little bit. Not even a tiny smidge. At all."
Earlier this year, Decker revealed that she doesn't like showing off her body because she is a "tomboy".
