(CNN) - Cardi B got so emotional.
Oh not just for her historic Grammys win as the first solo female rapper to win rap album of the year for her debut project "Invasion of Privacy."
This was a Grammys of firsts
That was pretty cool.
But early Monday morning, Cardi B shared a video on her Instagram account that also had her pretty moved.
In it the rapper can be heard saying "Oh my God" after her infant daughter Kulture utters the word "Mama."
"After a week of only saying papa !She saying mama!," the caption to the video read. "Happy 7 months Kulture ! We love you."
Kulture is the first child for Cardi B with her husband, Migos rapper Offset.
Cardi B thanked her baby during her Grammys acceptance speech and let the audience know "I'm not just saying thank you because she's my daughter."
"It's because, you know, when I found out I was pregnant, my album was not complete," the rapper explained.
"I had, like, three songs I was for sure having," she said. "And then you know how it was: We was like, We have to get this album done so I could shoot these videos while I'm still not showing. And it was very long nights."
