The 38-year-old's wife Ayda Field is due to give birth to their first child, a girl, next month and although he cannot wait to welcome her into the world, he is very nervous about the responsibilities of parenthood, reported Contactmusic.
"She's in my image, a mini-Robbie. I'm excited but in truth I'm scared," he said.
Earlier this week, the singer announced the release of a new solo album 'Take The Crown' and said he is more energised about his music career than ever.
"I haven't really been engaged in the past couple of albums but I'm really into this one. It might be because I didn't tour after any of them. I'm re-energised. I want to take over the charts and get my crown back.
