Dave Grohl Slammed As A 'Serial Cheater' & 'Scumbag' By Ex-Girlfriend Amid Love Child Scandal

Dave Grohl's ex-girlfriend, Kari Wuhrer, has labeled him a "serial cheater" in light of his recent revelation of a secret child, which has strained his 21-year marriage to Jordyn Blum.

Wuhrer claimed she was not surprised by the news and shared a story of how the rocker cheated on one of his exes with her.

Meanwhile, Jordyn Blum, who has remained silent, is reportedly considering a tell-all book about her marriage to Dave Grohl after his affair announcement.

In an interview with TMZ, Grohl's ex-girlfriend, Wuhrer, harshly criticized him as a "scumbag" and "serial cheater" after his love child confession.

However, the 57-year-old actress and model expressed little surprise at the news, noting that although she doesn't know the identity of the woman involved, she had heard rumors about Grohl's infidelity throughout his marriage.

Wuhrer, who dated Grohl in the late 1990s, recounted that he had pursued her while he was still in a relationship with snowboarder Tina Basich.

She recalled confronting Grohl on the "Howard Stern Show" about his unfaithfulness, which led the rockstar to shout at her.

Wuhrer revealed that her interview about Grohl led to a breakup between him and his then-girlfriend, Basich.

She noted, "I was letting the cat out of the bag... I never heard about her. He never spoke of it."

Wuhrer further mentioned that after Grohl yelled at her during the "Howard Stern Show" interview, he stopped talking to her.

According to Wuhrer, she and Grohl have since crossed paths in Los Angeles because their children attend the same play area, but the rocker allegedly acts like she does not exist.

"He would just look at me like I didn't exist," she told TMZ. "I just felt like I knew he was scumbag after that."

Wuhrer went on to advise Grohl to apologize to his exes and hopes he will be a responsible parent to his new daughter.

Meanwhile, Grohl's wife, Blum, has remained mostly silent since his disclosure of fathering a child with another woman.

However, the ex-model and producer is reportedly considering a lucrative book deal with a Simon & Schuster subsidiary following her husband's shocking revelation of infidelity.

Sources told the Daily Mail that if Blum accepts the offer, her book could detail her efforts to sustain their marriage for the sake of their three daughters: Violet, 18, Harper, 15, and Ophelia, 10.

"Jordyn has lots to reveal about being married to Dave," the insider said. "If she decides to accept the offer, it will be an intimate look at her life with a rock' n' roll icon for over twenty years."

They added: "She'll tell how she's been holding the marriage together for the sake of their three daughters."

Grohl's marriage to Blum came under scrutiny after the Foo Fighters frontman admitted he had fathered a fourth daughter with another woman.

In an Instagram statement, Grohl said: "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 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."

According to the Daily Mail, Blum "turned a blind eye" to Grohl's infidelities for a long time, but the latest revelation might push her to speak out about all she has endured in their marriage.

Prior to Grohl's affair announcement, the couple reportedly clashed over Blum's relationship with her married tennis coach, Christopher Crabb.

Sources told the Daily Mail that "Dave Grohl has been jealous for ages about Jordyn's hot tennis coach," adding, "They've had arguments about him, and Dave thinks they've flirted. Jordyn has told him he's crazy to even think that. But Dave has persisted."

Despite Blum dismissing his claims as absurd, Grohl remained suspicious, seemingly using these accusations to hide his infidelity.

"She gets coaching at least three times a week near the family home," the insider continued. "Jordyn now believes that Dave has been trying to detract from his own indiscretions by accusing her."

Blum has been training with Crabb for years at his $1.4 million Tarzana home, where he works with numerous celebrities. Recently, she was seen with the tennis coach after a session, notably without her wedding ring.
