Irish-American actress Megan Fox

Irish-American actress Megan Fox is reported to have signed on to play Catwoman in the upcoming untitled third “Batman” film.

Though last year rumor had it that British actress Rachel Weisz would step into the catsuit, according to Britain’s The Sun, “Transformers” star Fox will be the lucky one to join Christian Bale, Michael Caine and others in an all-star cast for the 2011 follow-up to “The Dark Knight.”

The 23-year-old starlet, whose heritage is a mix of Irish, French and Cherokee, and whose Irish ancestors came from County Tipperary, will follow in the footsteps of Michelle Pfeifer and Halle Berry if she in fact steps into the skintight catsuit and takes on the coveted role.

Fox, who was named FHM’s “Sexiest Woman in the World” in 2008, is fast becoming one of the most popular actresses of today.

Shooting for the newest “Batman” film is scheduled to begin next year.
