The 21-year old entertainer decided to change things up and shopped with a child-sized cart instead of a regular-sized one.

The week before, AJ was spotted out and about in Woodland Hills with big sister Aly.

“Let’s get to 500,000 [followers] by June 15th!!” Aly and AJ tweeted. “We can do it:) spread the word.”

FYI: AJ loaded up her cart with bottled waters and pet supplies.
