Ciara is already mom to son Future Zahir, 9, from her previous relationship with rapper Future, plus daughter Sienna Princess, 6, and son Win Harrison, 3, with her husband, Denver Broncos quarterback Russell Wilson.

Just last week, the couple announced that they were expecting their fourth child together and becoming a family of six.

In a video announcement on Instagram filmed by Wilson, 34, during the pair’s anniversary trip to Japan, Ciara was captured with a baby bump dancing around the edge of a swimming pool.

"You look at me like that again, we make another kid … You my heart I’m your rib” 🥰😘❤️,” she captioned the video of her silhouette with the matching lyrics from her song with Chris Brown, “How We Roll," playing.

In March last year, the couple previously told PEOPLE how life with three children is “non-stop entertainment”.

Ciara explained that they had a house packed with little comedians, saying, "These kids are funny. Our kids are really hilarious, and obviously the older they get, the more they think they know."

While the kids "run the house" at this point, their loving mom confessed it's youngest son Win who is "leading the charge" with his siblings.

"They say the third baby kind of moves or learns the quickest because they're trying to keep up with their siblings, and he's on it," Ciara told PEOPLE. "He's talking really early, he's moving, he's a big baby and he's really tall, you know?"
