Newly reunited spouses Offset and Cardi B welcomed their first child together, daughter Kulture, on July 10

The Migos rapper, 27, revealed the release date of his upcoming solo album and accompanying documentary on Sunday evening, sharing a video montage of himself in the recording studio, FaceTiming with his son, performing on stage — and being in the room during the July 10 birth of daughter Kulture Kiari, his first child with wife Cardi B.

In the latter clip, shown at the end of the montage, Offset stands behind Cardi B‘s shoulders as she gives birth, looking concerned as his wife yells out in pain and throws her head back.

Another angle shows him wearing a white hoodie while standing near the hospital room door, looking wide-eyed in shock before the camera zooms in dramatically and the video reveals the release date: Feb. 22.

Offset’s debut album will come two months after The New York Times reported it would be released: on the rapper’s 27th birthday, Dec. 14. After Quavo and Takeoff, he is the last Migos’ member to drop a solo record.

Two months after news that the pair had called it quits amid a cheating scandal — only to reunite repeatedly, including in Atlanta during the Super Bowl — Cardi B, 26, and Offset made their reconciliation red carpet-official at Sunday’s Grammy Awards.

Cardi and Offset posed for photographers before leaning in to share a lick. In one of the photos, Cardi — who wore a show-stopping pink and black Mugler design with an elaborate waistline and pearls wrapped around her neck and hair — held Offset’s hands and leaned in toward him to touch tongues.

In her acceptance speech for best rap album, the Invasion of Privacy hitmaker brought her beau onstage, where she thanked their daughter for helping make her dreams come true.

“I want to thank … the Migos, you, husband, thank you,” she said after expressing her gratitude for other artists who helped on her record. “Seriously, he was like, ‘You gonna do this album, girl. We gonna have this baby and we gonna make this album.’ ”

And their marriage is not for anyone except themselves. As Cardi B told PEOPLE of her relationship status in a candid interview in Atlanta ahead of the Super Bowl, “It’s a personal thing.”

“My relationship — my marriage — is not for [anyone else],” said the “I Like It” rapper — still, she added, they are “just taking things slow. We have a baby right now. That’s like our real big focus.”

“I hang out with him, I talk to him every day and we do our thing,” she continued of Offset. “To make things perfect … it takes time. You know, f—ing and hanging out doesn’t mean that you guys are on like a perfect note, it takes time. It takes time. And it’s a marriage and there’s a child involved and family involved.”
