The 29-year-old rapper gave birth to her kid in September and has tried to keep his face hidden from the public eye.
On Thursday, however, she turned to Instagram to share the well-dressed tot with the rest of the world.
A light blue puffer jacket with a fur-trimmed hood and a baby blue beanie cap were worn by the child.
He had a large piece of jewellery around his neck, much like his parents.
Offset then shared a photo of the kid in a bath seat, wearing even more bling, including a diamond stud earring, on his own Instagram account.
Wave Set Cephus was the child’s odd name, which was also disclosed by Offset.
Friends and fans of the celebrity flocked to the comment section to express their gratitude.
“Royal he already izz,” tweeted singer Art Rushiti, while American footballer Bradley Roby replied, “Yesssir.”
Offset and Cardi married in 2017 and have a daughter named Kulture Kiari Cephus, who is three years old.
The new photos back up Cardi’s social media post from last month, in which she revealed the family’s youngest member resembled his elder sister.
Wave, who was four months old at the time, had already begun to speak, she said in an Instagram Stories post earlier this year.
“I’m not kidding, this baby is talking,” she remarked at the time.
“In the name of Jesus Christ, I place this on everything I care about.” First and foremost, my spouse witnessed it.”
“You love Mommy?” she said she questioned the youngster. Several times, I was greeted with an exuberant “Yeah!” that couldn’t have been mistaken for anything else.
Cardi said she was close to having her son’s name tattooed on her before disclosing it. “Random but… I’m 1 percent close to tatting my son’s name on my face,” she stated in a tweet in January. It’s something I truly, really want to do!”
The actress said that she had opted to have the tattoo on her jaw.
The only other time fans saw the child was when the Rodeo singer shared an extreme close-up of one of his eyes on Instagram.
Cardi teased fans by adding, “That’s all y’all will get,” when they begged to see the baby.
