AceShowbiz - According to insiders, Dave Grohl has been "jealous" of his wife Jordyn Blum's relationship with her tennis coach, Christopher Crabb, for some time. The rocker has reportedly accused the two of flirting, despite Blum's denials. Grohl's alleged jealousy may have been an attempt to downplay his own infidelity, sources claim.

Grohl's jealousy reportedly stems from Blum's relationship with Crabb, whom she has trained with for years. "They've had arguments about him, and Dave thinks they've flirted," a source told the Daily Mail. Although Blum has repeatedly dismissed Grohl's suspicions as baseless, his persistence hints at underlying insecurities. Grohl's subsequent confession about fathering a baby with another woman further complicates the picture.

Grohl's announcement of an extramarital daughter came as a surprise to those close to the couple. However, sources suggest that his alleged infidelity was not entirely unexpected, given his past behavior. "We keep reading over and over again how heartbroken everyone is because Dave was supposed to be the 'good guy,' " a source said. "But there is a rockstar side."

After the scandal broke, Grohl's ex-girlfriend Tina Basich's previous claim about his unfaithfulness resurfaced. Basich alleged that Grohl cheated on her during their relationship in the 1990s. While Grohl's former bandmate Jennifer Finch has defended him as a good father, questions remain about his past and present conduct.

Blum has reportedly been devastated by Grohl's revelation. She has reportedly been receiving support from close friends, including Kate Hudson. "Her friends are like family, and they rallied around her," a source said.
