DAVE Grohl's ex previously spoke about the rockstar's alleged previous infidelity, which comes after the Foo Fighters star revealed he had fathered a secret love child.
"I've recently become the father of a new baby daughter, born outside of my marriage," the Foo Fighters rocker wrote in a bombshell statement on Instagram earlier this week.
"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," he continued.
"We're grateful for your consideration toward all the children involved, as we move forward together."
And now it has come to light that snowboarder Tina Basich, who previously dated the singer, claimed Dave cheated on her during their relationship.
Many years before Dave admitted to fathering a child outside his current marriage, Tina spoke of how he was always "busy" before revealing that he allegedly cheated on her.

In her 2003 memoir, "Pretty Good for a Girl: The Autobiography of a Snowboarding Pioneer," the now-55-year-old wrote about how Dave was allegedly romancing her and another woman at the same time.
Tina detailed how busy Dave was because of his "multimillion-dollar record contracts, deadlines with record labels, music videos [and] press tours".
She added that he worked on all of the above while "trying to maintain a focus on being creative and writing music."
"The pressure was too much for our relationship to handle," she admitted.

"You can only give up so much of your heart and your career and your time and your spirit, and here I was, giving it all up for a guy and losing myself in the process."
She then spoke of how he was "taking time away from his career" and also putting hers "in the backseat without even realizing it."
"I don’t know how anyone in his profession can have a normal relationship with a girlfriend…or two, as it turned out," she then revealed in the bombshell admission.
'EVERYONE ELSE IN THE WORLD KNEW ABOUT IT'
"I found out secondhand, through the grapevine, when it seemed like everyone else in the world knew about it but me.”
Tina then expressed her disappointment and said how she was "so disappointed and p**sed" because she got "sucked in".
The snowboarder dated the rocker, who is the same age as her, for two years in the late 1990s.
