'Liv & Maddie': Exclusive clip from Disney Channel's new comedy

What freaky twin thing?

There’s a new generation of lookalike blonds invading Disney Channel this fall: Liv and Maddie, a pair of polar opposites who just happen to be twin sisters. Mary-Kate Maddie is a wry, down-to-earth basketball star; Ashley Liv is a glamorous ex-TV star getting used to life as a regular kid. In this case, both girls are played by one actress: 17-year-old Dove Cameron, previously seen in bit parts on Shameless and The Mentalist. (She’s also got quite a voice.)

Get a sneak peek at the series premiere in the clip below, which shows the gals sharing some twin time. Maybe next they’ll discover that they both love Oreos dipped in peanut butter!

Liv and Maddie premieres on the Disney Channel Sunday, September 15
