The "Bronx Fairytale" themed celebration featured a custom bodega and even a replica of a 6 Pelham Bay Park Line cabin car, all tinted a shade of millennial pink in honor of Cardi's daughter due in July.
The two previously hinted at the baby shower in a recent Rolling Stone cover story which detailed the origins of their much discussed relationship.
"My baby shower's not starting at no 5:00," she said in the feature. "My shit is going to start at 9 p.m. because that's how I celebrate, that's how Caribbean people celebrate."
The "Bodak Yellow" hitmaker held to her word, and partied with family and friends for most of the night.
The hip-hop power couple made headlines earlier this week when it was discovered they had been married since September, one month before Offset proposed to Cardi at a sold-out show and nearly seven months after their first date at Super Bowl LI.
It was the same Super Bowl where Lady Gaga would perform her acclaimed Halftime Show if you happen to be asking for a friend.
