Frances Bean Cobain is now a mom.

The only child of late rock icon Kurt Cobain and rocker Courtney Love has welcomed her first baby with husband Riley Hawk, the eldest son of skateboarding legend Tony Hawk.

“9.17.2024 Ronin Walker Cobain Hawk,” Frances, 32, shared on Instagram Sept. 28, alongside photos of her and Riley’s baby boy and the proud dad holding the newborn. “Welcome to the world most beautiful son. We love you more than anything.”

Tony, now a first-time grandfather, commented, “My favorite grandson!” He also shared an identical birth announcement that Riley—whose mom is the athlete’s ex-wife Cindy Dunbar— had posted on his own Instagram page.

R.E.M. frontman Michael Stipe, Frances’ godfather, wrote, “With all the love and energy in the whole world.”

Frances also received congratulatory messages from Harper Grohl—whose dad Dave Grohl was Kurt’s friend and Nirvana bandmate—plus late actor Robin Williams‘ daughter Zelda Williams, Bruce Willis and Demi Moore‘s daughter Tallulah Willis, and KISS rocker Gene Simmons‘ son Nick Simmons, who wrote, “Love you fran, and very happy for you. the prophecy is fulfilled.”
