Foo Fighters frontman Dave Grohl is calling his unborn daughter "The Karate Kid" because she has such a powerful kick from inside his wife's womb.

The BEST OF YOU hitmaker and JORDYN BLUM are expecting a child in March (06), and the singer is amazed by how keen his child is to get into the outside world.

The father-to-be tells MTV Europe, "All I know is right now my baby is one of the most hyperactive children. I mean, she's not born, but I don't even have to feel my wife's stomach anymore. I just have to watch her shirt."

Rumours the couple were expecting had been circulating for months and were confirmed by bandmate Taylor Hawkins last month (JAN06).
