Have you heard of Liv and Maddie? It's the COOLEST new show to hit the screen and it's starting soon: October 11, 2013 to be precise.

Liv and Maddie Rooney are 15 year old twins who look identical, but couldn't be more different if they tried. Maddie is a sporty tomboy (that's her with the glasses) and Liv is a bubbly, girly teen TV star.

Liv has been away filming, and now she's back she and Maddie have to work out how to live and go to school together, without killing each other!

The craziest part? Both the twins are played by the same actor: Dove Cameron (with the help of some spesh effects). Poor Dove - she has to learn two sets of lines and switch back and forth between characters!

Fun fact: Dove's bestie is Olivia Holt!
