Madison Beer put her taut tummy on display in a white cropped T-shirt on Friday while running errands on Friday in Beverly Hills, California.
The singer completed her outfit with grey sweatpants and thick black combat boots.
Madison had her dark hair up in a high bun after recently going blonde over Christmas.
She accessorized with golden hoop earrings, watch and a necklace and accentuated her natural beauty with a hint of makeup.
Madison confirmed she was romancing Zack again Thursday with a very lovely Instagram post she shared via her Instagram stories.
