A Los Angeles-based rock ‘n’ roll fan has confirmed to the Post that she is the mother of Dave Grohl’s secret love child. Jennifer Young, 38, divulged that the Foo Fighters frontman, 56, fathered her baby girl — and records show that the little one, who was born on Aug. 1, 2024, has his last name. Young — a Florida-born music-lover covered in tattoos — has been living in a quiet, unassuming LA neighborhood with her mother. She is often seen taking her nearly 7-month-old daughter for walks around the block. Young requested that the baby’s name not be disclosed “because there’s some really angry fans.” “Protecting her identity is really important,” she said. Grohl’s rep did not respond to the Post’s request for comment. The musician — who has been married to wife Jordyn Blum since 2003 — shockingly revealed he welcomed a child with another woman in September 2024 — one month after the baby was born. “I’ve recently become the father of a new baby daughter, born outside of my marriage,” he announced on Instagram at the time. “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.” While Grohl vowed to be part of his daughter’s life, it’s unclear how much contact he has with Young. Although the two have never been spotted together, they were notably both in New York City over Valentine’s Day weekend. The “Everlong” rocker was in town for the “Saturday Night Live” anniversary concert and special. It’s unclear what brought Young to the big city or if the two met up. A former classmate described Young as “quiet” and “very pleasant,” but was shocked to learn of her connection to the rocker. “I feel like she was more into Gwen Stefani than the Foo Fighters,” they said. However, Young appears to be a big music lover, sporting tattoos of Paul McCartney lyrics and the Metallica logo. Her baby was also seen in a cranial helmet — a device often used to correct the shape of an infant’s skull — decorated with Metallica, Led Zeppelin and Elvis Presley stickers. Young does not have any public social media accounts, leaving little information about her private or professional life online. Along with the newborn, Grohl is also dad to daughters Violet, 18, Harper, 15, and Ophelia, 10, all of whom he shares with Blum. The former Nirvana drummer and Blum, 48, tied the knot at their Los Angeles home on Aug. 2, 2003 — the “My Hero” singer’s second marriage and the model’s first. Grohl’s affair was really “rough” on his wife of 21 years, who took off her wedding ring before the news broke and kept it off following the affair. “Jordyn is focused on her own life and her girls,” a source told People at the time. “Her mind is not on her marriage though. She doesn’t trust Dave,” they added. “She’s not wearing her wedding ring.” Although the rockstar hired a divorce attorney, he reportedly dropped the lawyer in November in hopes he could “work things out” with his wife. While he knew he “messed up,” he “loves his family” and didn’t “want to lose” them. Grohl and Blum were spotted together for the first time in nearly six months ahead of his trip to New York. On Feb. 11, the “Times Like These” rocker was photographed getting into Blum’s car after she picked him up from a house in Los Angeles. Grohl carried a duffle bag as he exited the home. The two seemed deep in conversation as they drove away. They both seemingly wore their wedding bands on their middle fingers rather than their ring fingers.
