Country star Taylor Swift has been tipped as the next big screen comic book heroine - she is rumoured to be in talks to play Supergirl.

The singer makes her film debut in upcoming romantic comedy Valentine's Day, and she recently admitted she would love to take on more acting roles.

And now Hollywood gossips are buzzing with rumours that studio executives want Swift to star in a remake of 1984 Superman spin-off Supergirl, which starred Helen Slater.

A source tells Hollyscoop.com, "Hollywood is short of female heroes and the time is right for a new Supergirl. A number of young stars are being mentioned for the title role in a Supergirl movie and possible TV spin-off and Taylor is top of that list. She has all the right elements to be a positive role model to young girls.”
