You wouldn't think a hard rock band would get all googly over a couple of precious little girls, but these are Dave Grohl's daughters we're talking about. 

Grohl (second from left) says his four-year-old daughter, Violet, would push the button on the coffee machine to make coffee for the Foo Fighters, who recorded an album at his house.

 He says his younger daughter, Harper, can't say "coffee," so she'd say "cotchee," so the band called it "cotchee" too.

Grohl says Violet would refer to the band as "the workers." He laughs that she would call legendary producer Butch Vig "a worker." Their album, "Wasting Light," is out this week.
