Foo Fighters frontman Dave Grohl shocked the music world last month when revealed he had a baby outside of his 21-year marriage to Jordyn Blum. An inside source has revealed to People that the past few weeks have “been rough” for Blum. “Jordyn is focused on her own life and her girls,” says the source. The 48-year-old Blum shares three daughters with the 55-year-old Grohl, Violet, 18, Harper, 15, and Ophelia, 10. “Her mind is not on her marriage though. She doesn’t trust Dave,” the source reveals. “She’s not wearing her wedding ring. She’s leaning on a group of girlfriends. She feels lucky to be surrounded by love and support.” Grohl, meanwhile, canceled his band’s scheduled appearance at the Soundside Music Festival on September 29 at the last minute, and was spotted without his own wedding ring when he was out running errands in L.A. on Wednesday (October 2).
