Foo Fighters star Dave Grohl's deafness is causing problems in his marriage because his wife has to repeat herself all the time. The former Nirvana drummer admits all rock star marriages have the same issue - because loud music kills normal conversation. Grohl tells women's magazine Elle, "Any woman who's going to date a rock musician has to be prepared to repeat herself every 10 seconds. "I'm virtually deaf... My wife asks me where we should go for dinner and it sounds like the schoolteacher from (TV show) Charlie Brown."
