A viral post by an Instagram user claiming she was the mother of Dave Grohl‘s “love child” has been confirmed to have been fake.

Earlier this week, the Foo Fighters revealed that he has become a father of a baby girl outside of his marriage  – but is “doing everything I can to regain the trust” of his wife Jordyn Blum and his family. He and Blum already share three daughters, Violet, Harper and Ophelia.

In an Instagram post, he also promised to be a “loving and supportive parent” to the child.

Shortly after the announcement, a post went viral from someone claiming she was the mother of Grohl’s fourth child, who said the child’s name was Roxie Junie Grohl.

The post featured a lengthy caption alongside a photo of a woman holding a newborn baby’s hand.

“My sweet Roxie Junie Grohl, being your mama has already been the most incredible experience of my life,” the caption began.

Later in the post, the creator said they could see Grohl’s face “like a little reflection of him in the tiniest, most beautiful way” when they looked at their child.

“From the shape of your eyes to the way your little nose crinkles when you smile, you are truly a Grohl through and through,” they alleged.

The post continued: “It’s amazing how much of him is already shining in you. Your dad is so proud that you carry on his family’s spirit, and I can already tell you have that same strength and kindness in you.”

A representative for Grohl has since confirmed to TMZ that the post is fake. Grohl has not commented on the identity of the mother of his fourth child or the child herself.

NME has approached Foo Fighters’ representatives for comment.

Violet and Harper have since deactivated their Instagram accounts. Violet has become known in recent years for touring with Foo Fighters alongside her father and is featured on the band’s 2023 track ‘Show Me How’ from their emotional album ‘But Here We Are‘ – written in the aftermath of the loss of Grohl’s mother Virginia and late Foos drummer Taylor Hawkins.

In January 2021, he hailed Violet as “an incredibly talented musician” who can “pick up an instrument and learn it within a week”. He added: “To be her drummer is one of my life dreams.”

In other Foo Fighters news, an Irish hitchhiker who is supposedly responsible for the formation of the band in the mid-1990s was recently identified.

The band are also set to perform at the Soundside Music Festival in Bridgeport, Connecticut, on September 29. Visit here for any remaining tickets.
