Carey revealed the 8-year-old's totally relatable choice on Instagram.
Carey kept things casual for their outing in black skinny jeans and a T-shirt, though she did add some glam with her signature stilettos.
Carey's Instagram followers loved everything about the cute photo, especially Monroe's choice.
"Oh don't tell me yal target bandits like me and my boys !!!!!" Jennifer Hudson commented on her photo.
"Watch What Happens Live" host Andy Cohen also joked that it was the "best ad for Target I've ever seen."
"Exactly!!! That's my daughter!!!" he commented on the photo.
Even Target got in on the fun, commenting, "We belong together."
Carey and Monroe have been getting in plenty of mom-daughter bonding time lately. A day before their Target trip, she shared this sweet photo of her "date night with Miss Monroe."
And she recently shared this cute photo of her twins hanging out at a recording studio.
There's no word yet on what Monroe bought during her Target shopping adventure, but no matter what, it looks like she had a fun day out with her mom!
