Lukas Graham Frontman Lukas Forchhammer Welcomes a Daughter

It’s a girl for Lukas Forchhammer!

The Danish singer and longtime girlfriend Marie-Louise “Rillo” Schwartz Petersen have welcomed their first child, a daughter, his rep confirms to PEOPLE exclusively.

The new mom took to Instagram on Saturday, sharing a photo of her newborn’s feet. “Good morning,” she captioned the sweet snap.

Forchhammer, 28, confirmed the happy news to PEOPLE in June.

“In September, a little golden nugget will be welcomed into the world,” the “7 Years” singer told PEOPLE at the time. “Seeing my child born is so much more important than anything else I’ve got going on.”

Shortly after the announcement, Schwartz Petersen celebrated the couple’s soon-to-arrive little girl with a mythical-creature-inspired baby shower.

“Current situation — there’s a pink unicorn in my kitchen,” she wrote next to a photo of herself wearing a sash emblazoned with the words “It’s a girl” and holding a unicorn-shaped balloon.

In August, Forchhammer joked to PEOPLE that Schwartz Petersen would need to be the one with the pipes in his daughter’s life.

“[Rillo] does the singing [and] I do the reading,” he said. “So that the [baby doesn’t] get confused [thinking] all parents are supposed to sing like that to their kids.”

Considering Forchhammer — who grew up in a hippie commune in Denmark, and considered a career in law before settling on music — isn’t huge on the spotlight and prefers life in Copenhagen over Los Angeles, it seems reasonable to assume his daughter will grow up to be just as humble as her dad.

“Fame wasn’t the driving force, money was never the driving force,” he told PEOPLE in April of what encouraged him to pursue music. “I feel like it’s ripping off the fan-base once the musician becomes more important than the music.”
