Christina Aguilera: Max-imum Maxfield's

Christina Aguilera and her adorable son Max do a little holiday shopping at the upscale shopping boutique Maxfield’s on Sunday afternoon (December 13)

Little Max walked out of Maxfield’s eating a pickle and was seen playing with the outdoors stone sculpture before being swooped up in Christina‘s arms.

Last week, the mother-son pair went Christmas Tree shopping together at Mr. Greentrees!
