“Sliders” actress Kari Wuhrer, 57, who dated Grohl in the late ’90s, had some not-so-nice things to say about the Foo Fighters frontman, 55, after discovering he had cheated on his wife, Jordyn Blum, and produced a love child with another woman.

The 55-year-old Foo Fighters frontman's past has come crashing into the present, with ex-flame Kari Wuhrer spilling secrets about Grohl's alleged decades-old infidelities, timed impeccably with his latest fatherhood announcement.

Kari, 57, who dated the Foo Fighters singer in the 90s, wasn't surprised to hear that Dave had been unfaithful to his wife of 21 years, Jordyn Blum. She told TMZ that Dave, now 55, was seeing her while he was also dating his ex-girlfriend Tina Basich.
