Sounds like someone else has been getting the best of Dave Grohl. The Foo Fighters singer confessed in an Instagram post that he “recently†had a daughter “born outside of my marriage.†“I plan to be a loving and supportive parent to her,†Grohl continued. “I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness. We’re grateful for your consideration toward all the children involved, as we move forward together.†Grohl, 55, has been married to his second wife, Jordyn Blum, since 2003, and they share three daughters. (He and his first wife, Jennifer Youngblood, split in 1997 over his infidelity.) It’s unclear why Grohl is admitting this now, on his dormant Instagram account, @davestruestories in the same font he used to promote his memoir. Do TMZ and the Daily Mail know something? Regardless, between this and the Linkin Park mess, it’s a bad time for your late ‘90s and early ‘00s rock-radio faves.
