Cardi B and Offset are celebrating their baby boy on his special day.

On Wednesday, Sept. 4, the proud parents separately took to Instagram to honor their son Wave Set as he turned 3 years old amid their public divorce after six years of marriage.

Sharing a plethora of pictures from their little one’s recent airplane-themed birthday party on their respective accounts, the rapping duo raved over their son on his big day.

In Cardi’s post, the pregnant “I Like It” singer, 31, can be seen holding Wave in her arms with her bare baby bump on display, as she awaits the birth of her third baby. “Happy birthday to my son Wavey Man,” she wrote in her caption.

Cardi continued to admit that she was “so scared” to have a boy, writing, “I was soo happy when I found I was having a baby then all of a sudden I got so scared when I found out I was having a boy I’m such a girly girl. You make it easy tho getting into that sporty mom bag.”

“My baby love his momma soo much .Ill always have your back ,front and sides BIG WAVE,” she concluded her caption.

The soon-to-be mom of three also included a sweet throwback video in her post, showing a newborn Wave as Cardi held him and fed him his bottle.

Offset, 32, shared more adorable snaps from Wave’s birthday bash, including multiple of the father-son duo showing off their moves on the dance floor, and posing with his step-brothers Jordan, 14, and Kody, 9, whom Offset welcomed in during previous relationships.

Cardi and Offset’s older child, daughter Kulture, 6, is also highlighted in the post as she gives her little bro a big hug before the party.

“God Greatest Gift is a child…..” Offset said in his caption, adding, “My youngest turned 3 today happy bday Wave Set love you son son !”

Offset is also a dad to daughter Kalea Marie, 9, from a previous relationship, who can be seen holding hands with Kulture in the background of Offset and Cardi’s pictures.
