Cardi B gives birth to baby No. 4, her first with boyfriend Stefon Diggs

The “WAP” rapper, 33, stepped out at Cybex’s NYC flagship store launch on Thursday, making her first public appearance just days after giving birth to her fourth child, her first with boyfriend Stefon Diggs.

She wowed onlookers in Dilara Findikoglu’s cropped Matter of Time bomber jacket (£2,620, about $3,445) with a cinched waist that flashed her bare midriff and lower back.

Cardi confirmed that she’d welcomed a son with Diggs, 31, in an Instagram post prior to the event, writing that she brought “a new baby into my world, and one more reason to be the best version of me, one more reason to love me more than anything else or anyone else so I can continue giving my babies the love and life they deserve.”

According to TMZ, the New England Patriots wide receiver was by her side when she gave birth last week.

In an Instagram Stories clip from the event, Cardi gushed about Cybex’s pink strollers covered with 3-D flowers. “I love this stroller! I wish I would’ve known about this stroller last year,” she said in one video, before pointing to a toddler-sized model and declaring, “Alright I’ll get this one for Blossom.”
