AceShowbiz - Dave Grohl's personal life continues to be under scrutiny following his bombshell admission that he has fathered a baby born outside of his marriage. While the singer has kept the identities of his child and baby mama a secret, a new report has revealed details of his alleged side chick.

According to Media Take Out, the 55-year-old musician had an affair with a black woman, who eventually carried and gave birth to his baby girl. The "dark skinned" woman is further described as "tall and beautiful," but her name remains unknown.

The details of Dave's baby mama surfaced after an Instagram post claimed that a baby girl named Roxie Junie Grohl was the Foo Fighters frontman's newborn daughter. The post was first shared on Wednesday afternoon, September 11 by an Instagram account for a user named @valeriegreyson.

In the post, the user shared an image of a baby in a car seat holding a woman's finger. The caption read, "my sweet Roxie Junie Grohl, being your mama has already been the most incredible experience of my life." It went on to claim, "Your daddy, was by my side through the entire pregnancy, making sure we were both taken care of, and I'm so grateful for his love and support."

Further making it obvious whom the user was referring to as the baby's father, they added "davegrohl" as one of the hashtags.

However, a representative for Dave has told TMZ that the post purportedly showing the singer's baby girl is fake.

Dave, who has been married to Jordyn Blum since 2003 and shares three children with his wife, dropped the bombshell news on Tuesday. "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," he said in a statement.

Declaring his commitment to his wife and family, the rocker added, "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."
