It’s a baby party: Ciara is a mom!

The “Body Party” singer welcomed her first child with her fiancé, rapper-producer Future, on Monday, she announced via Facebook.

“Future Zahir Wilburn, 9 lbs., 10 oz., May 19, 2014,” she wrote, sharing a photo of the newborn’s arm.

Afer months of speculation that the couple — who were engaged in October — were expecting a baby, Ciara, 28, finally put the rumors to rest by showing off her baby belly during a visit to The View in January.

Days later, Ciara got glamorous for an appearance at the Grammys. In March, the singer celebrated her baby shower with pals, including La La Anthony and Kim Kardashian, and revealed she was expecting a boy.

In April, Ciara stepped out for Safe Kids Day, telling PEOPLE about her maternity style — and admitting she was over heels at that point.

“I like to be free and comfortable and relaxed. I don’t want to feel stressed. It’s already so much with your belly being so big,” she said at the time.

“When I have to get cute, I will get cute and put on some heels for an hour or two — and then throw those things off as soon as I get in the car!”
