Baby's day out!

New mom Beyonce enjoyed another low-key NYC afternoon with some of her favorite girls Monday -- mom Tina Knowles and daughter Blue Ivy!

For her family outing, the "Love on Top" singer, 30 -- who gave birth January 7 -- rocked vibrant, printed pants and accessorized with gold hoop earrings and a fedora.

Earlier in the week, the trio hit Brooklyn's Prospect Park with pals, where they relaxed on the grass. "It seemed like a family day! They were chilling," an eyewitness told Us Weekly of the laid-back group. "They had a blanket out."
