LOS ANGELES — Dave Grohl says he recently fathered a daughter outside his 21-year marriage to Jordyn Blum, with whom he has three older daughters.

'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,' the Foo Fighters front man and former Nirvana drummer said Tuesday in an Instagram post. '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.'
