The 28-year-old singer, real name Lukas Forchhammer, has welcomed a baby girl, ET confirms.
Graham's girlfriend and high school sweetheart Marie-Louise "Rillo" Schwartz Petersen took to social media on Saturday to confirm the news.
"Good morning ?," she captioned the sweet snap of their daughter's tiny feet.
The longtime couple was definitely prepared to welcome their little one after celebrating their baby shower in June.
"It's a girl ?????? tak for et fantastik baby shower ?," Schwartz Petersen captioned a few pics of the pink-themed affair.
"Current situation - there's a pink unicorn in my kitchen?????," she wrote alongside another snap.
Graham isn't the only musician to welcome a bundle of joy. Atlanta creator and star Donald Glover -- who raps under the name Childish Gambino -- quietly welcomed a child earlier this year.
