Cardi B has thrown a massive mermaid themed birthday party for her 4-year-old daughter, Kulture Kiari Cephus.

The 29-year-old rapper took to Instagram Sunday to share a series of photos from the event, including snaps of the birthday girl, who turned 4 on July 10, dressed as a marmaid.

The carousel of images also include family photos showing Kulture kissing her mom and having a great time with her father, 30-year-old rapper Offset, and 10-month-old brother, Wave Set.

In the photos, one can see Cardi B wearing pink hair and a pinkish mermaid-themed dress. Wave Set, on the other hand, dons a printed white shirt paired with white pants. As for Offset, he's pictured wearing a casual black sweatshirt and matching shorts.

"I got your back, your front and sides," Cardi B wrote in the caption. "BIG 4."

Fans were quick to share their reactions to the fun-filled photos.

"Adorable! Her birthday parties be a movie! Sheesh, just imagine when she turn 16," one of the fans wrote, while another one said, "Thank you for doing it for the kulture… much love..your kids will be stars."

Offset created a buzz last week for posting a video of Kulture receiving $50,000 in cash from her parents. The video was later shared by a fan on Twitter.

It wasn't the first time the couple made headlines for their extravagant cash gifts. When Offset celebrated his birthday in December last year, the "WAP" artist gifted him with a $2 million check. She also annouced at the time that her husband was going to be involved in a lot of businesses the following year, so she wanted to give him some money.

"You have soo many projects and businesses that you are managing and leading yet you have helped me so much in this journey wit our two babies," she added.

The couple had a secret wedding in September 2017 and kept their union under the wraps until a year later. Cardi B then gave birth to Kulture on July 10, 2018.

In September 2020, Cardi B filed for a divorce, accusing Offset of infidelity. However, she dismissed the filing just two months later. The pair then welcomed Wave Set in September 2021.
