Dave Grohl was ‘jealous’ of wife Jordyn Blum’s ‘flirty’ relationship with ‘hot’ tennis coach: report

Dave Grohl was reportedly “jealous” of his wife Jordyn Blum‘s “flirty” relationship with her “hot” tennis coach.

The Foo Fighters rocker — who announced last week that he welcomed a baby outside his marriage — had been grilling Blum about her relationship with Christopher Crabb in an attempt to diminish his own infidelity, according to the Daily Mail.

“Dave Grohl has been jealous for ages about Jordyn’s hot tennis coach,” a source told the outlet Saturday.

“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.”

Blum, 48, has been working with Crabb, 55, for years, per the outlet, and sometimes has multiple sessions per week at his $1.4 million mansion in the Tarzana neighborhood of Los Angeles.

The “Danger Bay” actor also coaches several other celebrities, including Donald Faison, Jeff Probst, Steve Carell and siblings Elle and Dakota Fanning.

In July, Crabb posted a snap on Instagram of Grohl and his wife looking happy at Wimbledon, writing: “So excited to see my students, Dave and Jordyn. They always look stylish on and off the tennis court.”

Last week, Grohl, also 55, shocked the world when he announced that he had fathered a child with an unidentified woman who is not his wife.

“I’ve recently become the father of a new baby daughter, born outside of my marriage,” he wrote on Instagram on Sept. 10.

“I plan to be a loving and supportive parent to her. I love my wife and my children, and I am doing everything I can to regain their trust and earn their forgiveness.”

Before the bombshell, the former Nirvana drummer had reportedly hired a divorce lawyer, and Blum had been seen without her wedding ring on.

The Post reported last Thursday that Grohl once grew close with adult film industry star Annaliese Nielsen — and that her ex-roommate Tyler Ammons saw the musician getting cozy with her in 2018.

Ammons said he thought it was “very weird” when he saw them “very close on the couch.”

“I obviously knew who he was when I walked in. I felt uncomfortable knowing he has family and children, and I left,” he added.

Blum and Grohl tied the knot in 2003 and recently celebrated their 21st wedding anniversary.

The couple shares three daughters together: Violet, 18, Harper, 15, and Ophelia, 10.
