Dave Grohl, the 55-year-old frontman of the Foo Fighters and former Nirvana drummer, announced on Instagram that he recently fathered a baby girl outside of his 21-year marriage to Jordyn Blum. In his statement, Grohl expressed his intention to be a “loving and supportive parent” to his new daughter while working to regain the trust of his wife and children.

The rock icon did not provide further details about the mother of the child but asked for privacy, stating, “We’re grateful for your consideration toward all the children involved, as we move forward together.” Grohl has three daughters with Blum—Violet Maye, 18, Harper Willow, 15, and Ophelia Saint, 10—whom he referenced in his message as he emphasized his love for his family and commitment to repairing their relationship.

A representative for Grohl offered no additional comments regarding the announcement. Grohl has been widely admired for his career with Foo Fighters and Nirvana, and this personal revelation marks a rare insight into his private life. While Grohl’s message was clear about his dedication to his family, the lack of further details about the situation leaves many questions unanswered.
