Disney's new show, "Andi Mack" has a surprise twist + watch the premiere

Thirteen year old Andi Mack is surprised when her older sister Bex returns home and reveals something mindblowing - she's actually her mother, and her mother is her grandmother. The show will gradually reveal Andi's biological father over the thirteen episode first season. They won't talk about sex - or the fact that Bex clearly got pregnant as a teenager - but the show is about relationships. The official premiere is April 7th.
