Christina Aguilera is all smiles while taking son Max to the Walt Disney World Resort in Florida.

The former Mousketeer and her little boy snapped this photo at Disney's Animal Kingdom. Looks like Max scored Mickey ears, too! Just last week, lil' Max hung out with daddy Jordan Bratman ... even cruising with dad to go buy some Patron.

X-tina is spending as much time with Max before she begins her new gig on NBC's The Voice. Find out when the show premieres ... after the jump.
