There goes my hero.

Foo Fighters frontman and former Nirvana drummer Dave Grohl has announced that he fathered a child out of wedlock. In a September 10 Instagram post, Grohl wrote, “I recently became the father of a new daughter, born out of wedlock.”

He went on to explain that the extramarital affair and child have not shaken his devotion to his wife, Jordyn Blum, and their three daughters. “I love my wife and my children, and I am doing everything I can to earn their trust and earn their forgiveness.” He also indicated that he would be a force in his new daughter’s life as well: “I plan on being a loving and supportive parent to her.”

Grohl’s representatives had nothing to add when asked for comment by Weekly entertainment.

The post was a rare one from Grohl, whose social media presence is limited to Instagram. That account only launched in 2020 and has 22 posts in total, 20 of which relate to the memoir The Storyteller Grohl was released in 2023. He frequently appears in photos posted to the Foo Fighters Instagram account.

Grohl’s wife of more than 20 years, Jordyn Blum, is a former model and MTV producer. Blum has remained even more out of the spotlight than Grohl, but has worked on several Foo Fighters projects, including appearing in the music video for the 2011 song “White Limo” and co-directing the music video for the 2002 song “Walking a Line.”

Grohl has publicly identified his wife as the inspiration behind several Foo Fighters songs before, though not always positively. In a 2006 interview with The AV clubGrohl cited the 2002 song “Burn Away” as a song that now makes him “chuckle,” explaining, “I was in love with my future wife and had this romantic f—ing prom ballad. Yuck! We would never play that f—ing sh– live.”

Grohl and Blum have three children together: Violet Maye (born 2006), Harper Willow (born 2009) and Ophelia Saint (born 2014). Violet, now 18, is a musician in her own right, and occasionally joins her father onstage for Foo Fighters performances, as she did during their Glastonbury set in 2023.

Grohl has recently had a public feud with two of the most famous people in the world: Taylor Swift and Donald Trump. He incurred the wrath of the Swifties when he suggested during a June concert that her Eras Tour band not perform live. Trump and the Foo Fighters, meanwhile, have clashed over whether the former president’s campaign had permission to use the song “My Hero” at a recent rally.

Neither Blum nor Grohl’s bandmates, Nate Mendel, Rami Jaffee, Chris Shiflett, Pat Smear and Josh Freese, have commented on Grohl’s affair and new daughter.
