Grohl, 55, did not share further details about the baby or her mother, and his representatives declined to comment.

Grohl married Blum, a former model turned film and television producer, in 2003. They have three daughters, including 18-year-old singer Violet Grohl, and a child, ages 15 and 10.

He was previously married to photographer Jennifer Leigh Youngblood, from 1994 to 1997, and has acknowledged that infidelity led to their divorce.

Grohl formed the Foo Fighters in 1994, shortly after the death of Kurt Cobain put an end to Nirvana. In 2022, the band’s longtime drummer and Grohl’s best friend, Taylor Hawkins, died during a tour of South America.
