The 42-year-old actor welcomed son Robert with girlfriend Jade Buell last month. He told Access Hollywood that he didn't used to be a fan of newborns, but now he thinks their cries are 'like beautiful music'.
He said, 'I was never like somebody who was like, 'Oh gosh, it's a little baby! Let me hold it,'' he said.
'They're so fragile, but then when it is your own, all of a sudden you feel a lot more confident. You really do have this bond, this real connection with this thing that a month ago wasn't even here… It is strange... Their cries are like beautiful music.' He added that he finds it impossible to tell if Robert looks more like his mum or dad.
'Babies look a lot more like other babies than they ever do like their parents. That's what I've begun to notice,' he said.
