On Thursday, the rapper duo announced the name of their son: Wave Set Cephus.

They also shared adorable photos of him on their respective Instagram pages.

The Bodak Yellow rapper captioned her post with emojis of a wave, a teddy bear, and a blue dinosaur alongside pics of Wave rocking a blue fur-lined coat and massive diamond chain.

Her hubby shared another priceless pic of the infant looking up at someone off-camera, again sporting an impressive amount of blinged-out necklaces.

Cardi took to Twitter to further reveal that Wave's dad was the one who came up with the unique moniker for their son.

"When Set suggested Wave, I was sold! THAT HAD TO BE HIS NAME !" she tweeted, with a video of an impressive piece of diamond-encrusted jewelry that spelled out her son's name.

During a recent interview with Essence, the couple, who wed in 2017, explained why they chose to wait to reveal their son's name.

"We went through a lot of sad things when it comes to our daughter Kulture - terrible behavior that not even the older kids have ever been through," Cardi remarked. "So many people will post mean, disgusting things, just to get a reaction from us."

The I Like It rapper added, "We want to protect our feelings, because we get very, very angry and upset."

One thing is for certain: good looks and classy style definitely runs in this family!
