The instructor quickly made headlines after Dave Grohl’s scandal broke, with rumors that the “hot” tennis coach had a “flirty” relationship with Jordyn Blum.

Dave Grohl’s ex, Kari Wuhrer, says she’s heard “rumblings” about the rocker’s infidelity in his marriage to Jordyn Blum before it was revealed that he had a baby girl with another woman. Wuhrer, an actress best known for her parts in Anaconda and Thinner, told TMZ that there had been chatter around Hollywood about Grohl's cheating ways for years.

Some believe Jordyn Blum may have known about Dave Grohl's infidelity long before he came clean, an insider tells The Post.
