Rocker Dave Grohl: New Daughter Is 'Loud as Hell'
Harper Willow Grohl is named after Grohl’s great uncle Harper Bonebrake and, according to dad, is "7 lbs. 8 oz., 20-inches long and loud as hell."
Harper joins 3-year-old big sister Violet Maye, who will hopefully influence her new sibling's taste in music.
"Violet loves the Amy Winehouse record," he told PEOPLE last fall. "It's all about the 'Rehab' song. If she hears 'Try to make me go to rehab,' Violet will go, 'No no no.' I know, it's a little weird, but it's really cute!"
