THE mother of Dave Grohl’s love child has been revealed after he admitted to a secret affair.

The Foo Fighter’s rocker fathered the infant with a 38-year-old rock ‘n’ roll fan called Jennifer Younger, according to reports.

The NY Post has viewed documents showing the baby girl, who was born in August of last year, shares Grohl’s last name.

The blonde woman is said to have tattoos of Paul McCartney lyrics and the Metallica logo.

While the little girl was seen with a helmet featuring stickers of Elvis and Led Zepellin.

Last year Dave, 55,  shocked fans when he told how he had fathered a secret daughter outside of his marriage.

He pledged to “regain the trust” of his wife Jordyn and their three daughters – and also said he planned to support his new child.

The former Nirvana drummer wrote on Instagram: “I’ve recently become the father of a new baby daughter, born outside of my marriage.

“I plan to be a loving and supportive parent to her. I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness.”

The rocker has been married to director and actress Jordyn, 48, since 2003.

Together, the two stars are parents to daughters Violet Maye, 18, Harper Willow, 15, and 10-year-old Ophelia Saint.

His first marriage ended in 1997 after three years after he admitted cheating.

Despite his affair, Dave is said to have spent the Christmas period with his wife and kids.

People reported beforehand that an insider revealed: “They are all spending Christmas as a family.”

Another insider also spilled: “Dave’s been prioritizing his family. He knows he messed up.

“It’s one of those situations where you don’t realize what you have until you’re about to lose it.

“He doesn’t want to lose his family.”
