Kurt Cobain's daughter and Tony Hawk's son have welcomed their first child together.

Frances Bean Cobain, the 32-year-old daughter of the late Nirvana frontman, confirmed in an Instagram post on Saturday that she welcomed a child with her husband Riley Hawk, the famed skateboarder's 31-year-old son.

She shared multiple photos of the baby boy, who was born on Sept. 17, including one of him being held by his father. Cobain also posted the photo in an Instagram Story accompanied by the John Lennon song "Beautiful Boy (Darling Boy)."

"Ronin Walker Cobain Hawk," she wrote. "Welcome to the world most beautiful son. We love you more than anything."

Tony Hawk celebrated the news in an Instagram comment, writing, "My favorite grandson!" Harper Grohl, whose father is Nirvana alum Dave Grohl, also commented with heart and teary, smiling emojis. "With all the love and energy in the whole world," R.E.M. frontman Michael Stipe, Frances Bean's godfather, wrote.

Kurt Cobain died by suicide in 1994, when his daughter was 20 months old. In an Instagram post in April, she reflected on the 30th anniversary of his death and shared photos of their time together.

"I wish I could've known my Dad," she wrote at the time. "I wish I knew the cadence of his voice, how he liked his coffee or the way it felt to be tucked in after a bedtime story. I always wondered if he would’ve caught tadpoles with me during the muggy Washington summers, or if he smelled of Camel Lights & strawberry nesquik (his favorites, I've been told)."

"But there is also deep wisdom being on an expedited path to understanding how precious life is. He gifted me a lesson in death that can only come through the LIVED experience of losing someone. It's the gift of knowing for certain, when we love ourselves & those around us with compassion, with openness, with grace, the more meaningful our time here inherently becomes."

She added that her father wrote her a letter before she was born that ended with the message, "Wherever you go or wherever I go, I will always be with you."

"He kept this promise because he is present in so many ways," she said. "Whether it's by hearing a song or through the hands we share, in those moments I get to spend a little time with my dad & he feels transcendent."

In a 2019 interview on the "RuPaul: What’s the Tee?" podcast, Cobain shared she felt guilt about inheriting money from her father.

"My relationship to money is different because I didn't earn it," she said. "It's almost like this big, giant loan that I'll never get rid of. I have an almost foreign relationship to it or guilt because it feels like money from somebody that I've never met, let alone haven't earned myself."
