Dave Grohl’s ex-girlfriend Kari Wuhrer blasts him as ‘scumbag’ and ‘serial cheater’ after secret baby threatens his marriage with  Jordyn Blum

Dave Grohl’s ex-girlfriend Kari Wuhrer has slammed him as a “villain” and a “serial cheater” after his secret baby bombshell jeopardized his marriage to Jordyn Blum.

The 57-year-old actress and model responded directly to the recent scandal surrounding the 55-year-old Nirvana drummer, saying she is not surprised by the news.

She told TMZ Thursday that she may not know the identity of the woman with whom Grohl admitted to secretly having a child, but that there have been “rumors” that he may have been unfaithful to his wife of 21 years.

Kari dated Dave during the Foo Fighters’ heyday in the late 1990s. She told the publication that Grohl approached her while she was dating Tina Basich.

Kari, who told TMZ the musician was an “asshole” and a “serial cheater,” said she learned the truth about his “deceptive behavior” when she called into The Howard Stern Show at the time and expressed her frustration over the relationship with the shock jock, prompting the rock star to yell at her.

She said Tina found out about the interview, leading to a rift between the now 55-year-old snowboarder and Grohl.

Kari explained to the publication, “I let the cat out of the bag… I never heard about her. He never talked about it.”

She also claims the Foo Fighters frontman never spoke to her again after he yelled at her.

However, she said they met in Los Angeles because their children happened to go to the same playground.

Kari said, “He just looked at me like I didn’t exist. I just felt like I knew he was a scumbag.”

She told TMZ that she would advise Grohl to apologize to all of his exes following the latest news about his life and that she hopes the rock star will stick up for his new daughter.

This comes as Grohl’s wife Blum has remained somewhat silent since he destroyed their 21-year marriage with his shocking admission that he fathered a child with another woman.

Kari (pictured in July 2014) – who told TMZ the musician was an “asshole” and a “serial cheater” – said she learned the truth about his “double timing” when she called into the Howard Stern Show at the time and expressed her frustration over the relationship with the shock jock, which led to the rock star yelling at her

But now she could reveal her relationship with the disgraced Foo Fighters rocker, after being paid a large sum for a revealing book.

The 48-year-old former model and producer is said to be considering a multimillion-dollar offer from a subsidiary of publishing giant Simon & Schuster after feeling “humiliated” by her husband’s confession.

Insiders have told DailyMail.com that if Blum agrees, she could reveal how she “keeps the marriage together” for the sake of their three daughters: Violet, 18, Harper, 15, and Ophelia, 10.

“Jordyn has a lot to reveal about her marriage to Dave,” they said. “If she decides to accept the offer, it will be an intimate look at her life with a rock ‘n’ roll icon for more than two decades.

“She will tell how she keeps the marriage together for the sake of their three daughters.”

Grohl and Blum’s seemingly rock-solid marriage – and his image as “the nicest guy in rock” – were thrown into disarray earlier this month when he revealed he had fathered a fourth daughter with an unknown woman.

“I recently became the father of a baby girl, born out of wedlock,” he wrote in a statement on Instagram. “I plan to be a loving and supportive parent to her.

“I love my wife and my children, and I am committed to earning their trust and forgiveness. We are grateful for your attention to all the children involved as we move forward together.”

Blum could be set to go public with her marriage to Dave Grohl after receiving a large sum of money for a revealing book, insiders told DailyMail.com

A few days later, his alleged relationship with 40-year-old porn publisher Annaliese Nielsen came to light. Her former friends told DailyMail.com that she had a 15-year affair with the frontman.

Blum reportedly “turned a blind eye” to Grohl’s behavior during their marriage, but she may be able to say something about it after the latest revelations.

“Close friends believe she has been turning a blind eye to Dave’s indiscretions for a long time,” the insider said.

‘Now that he has humiliated her in front of the world with his baby bombshell, she can no longer hide behind the facade of a perfect marriage.’

They claimed that other publishers have also contacted Blum to discuss possible book deals.

Grohl released his autobiography, The Storyteller: Tales of Life and Music, in October 2021.

A collection of short stories and anecdotes, the book chronicles his childhood in suburban Virginia, his rise to fame with Nirvana, and the formation of the Foo Fighters. It topped the New York Times bestseller list and was named one of the best music books of 2021 by Variety.

But it was criticized for its lack of coverage of Nirvana, the late Kurt Cobain and for not mentioning his first wife Jennifer Youngblood. The couple were married for three years before splitting in 1999 over his infidelity.

He then dated Louise Post of the band Veruca Salt, who accused him of cheating on her with actress Winona Ryder and a handful of other women.

He recently had a falling out with Blum over her “flirty” relationship with her married tennis coach Christopher Crabb, in what insiders say was an attempt to distract from his own misdeeds.

“Dave Grohl has been jealous of Jordyn’s handsome tennis coach for some time now,” an insider previously told DailyMail.com.

“They had a fight about him, and Dave thinks they flirted. Jordyn told him he was crazy to even think that. But Dave moved on.”

Blum has been training with Crabb for years, sometimes holding as many as three sessions a week at his $1.4 million Tarzana estate, where he trains a host of celebrities, including Pete Wentz, Hillary Duff and Zach Braff, on his bright blue tennis court.

She was photographed with the coach, a former actor, earlier this week after a session, not wearing her wedding ring.
