Dave Grohl’s ex Kari Wuhrer not surprised that 'cheater' had child outside of Jordyn Blum marriage

Dave Grohl has been a "Pretender" for years, according to his ex, Kari Wuhrer. 

Kari Wuhrer spoke to TMZ on Thursday about her ex allegedly fathering a child outside his marriage to Jordyn Blum, claiming she had “heard rumblings” of the Foo Fighters frontman’s supposed infidelity for years.

The 57-year-old model was romantically involved with Grohl, 55, during the 1990s when he was also in a relationship with Tina Basich.

However, Wuhrer claimed she was unaware that the musician was also dating the 55-year-old snowboarder during their time together.

“I never heard about her,” she told the outlet. “He never spoke of it.”

In fact, she revealed that she was the one who inadvertently “let … the cat out of the bag” after calling into the “Howard Stern Show” to complain about the Nirvana drummer yelling at her.

Basich ended her relationship with Grohl upon learning about the radio show — and Wuhrer said she never heard from him again.

Years later, when the two crossed paths while taking their children to a play area, Wuhrer alleged that Grohl “would just look at [her] like [she] didn’t exist.”

Wuhrer added, “I just felt like I knew he was a scumbag after that.”

Grohl’s personal life has come under scrutiny since he admitted to fathering a child in a statement on Instagram last week.

“I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness,” the Grammy winner wrote, referring to Blum and their daughters — Violet, 18, Harper, 15, and Ophelia, 10.

While Grohl has not provided any further details, his representative denied a viral claim from a social media user alleging she was the mother of his newborn daughter.
