Dave Grohl’s ‘flirty behavior’ was ‘hurtful’ to wife Jordyn Blum long before secret love child: report

Dave Grohl’s alleged flirtatious behavior toward other women was reportedly “hurtful” to his wife, Jordyn Blum, long before he secretly welcomed a baby with a mistress.

“Dave’s flirty behavior has been a hurdle in their marriage,” an insider told People Monday. “It’s been hurtful to Jordyn.”

Another source close to the couple explained that the Foo Fighters singer’s love child didn’t come as a complete shock to those in his and Blum’s circle.

“We keep reading over and over again how heartbroken everyone is because Dave was supposed to be the ‘good guy,’ the rockstar that didn’t have to do those rockstar things,” the insider told the outlet.

“And people are crazy about the guy, but there is a rockstar side.”

The source added that Grohl, 55, and Blum, 48, “felt like an opposites attract type of [relationship].”

A third insider claimed that Blum “was shocked when she found out about the baby.”

“Her friends are like family, and they rallied around her,” the source said.

Reps for Grohl and Blum did not immediately respond to Page Six’s requests for comment.

But the flirtatious behavior was allegedly not one-sided as the rocker was reportedly jealous of Blum’s “flirty” friendship with her “hot” tennis instructor.

Grohl and his wife — who tied the knot in 2003 — share three daughters.

Last week, the Grammy winner announced that he fathered a daughter outside of his marriage, though he didn’t disclose details of his affair.

“I plan to be a loving and supportive parent to her,” he wrote via Instagram on Sept. 10. “I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness.”

Ahead of the revelation, the rock star reportedly hired a divorce lawyer, and his wife was seen without her wedding ring.

Blum has reportedly confided in close pal Kate Hudson amid the bombshell news.

Though the identity of Grohl’s mistress hasn’t been revealed, The Post uncovered the singer’s past friendship with Annaliese Nielsen, an adult entertainment star.

“She had pictures … she [had a relationship] with him for years,” an insider explained. “She would say, ‘He paid for all my bills.’ It’s like, ‘Why are you telling us this?'”

Nielsen denied being the woman currently involved in Grohl’s love triangle and claimed they only had a “brief friendship.”
