Andi and Bex is the pairing between Andi Mack and her mother, Bex Mack. Andi and Bex's relationship forms the core of the show. While this is a mother-daughter relationship, it comes off as a sister-sister relationship because Andi grew up believing that Bex was her sister. Even after revealing the secret to Andi, Bex still acts more like Andi's older sister as opposed to her mother. Andi and Bex are portrayed by Peyton Elizabeth Lee and Lilan Bowden respectively.
