The 'Angels' singer is very excited about the impending arrival and said Field had asked him to keep quiet about the gender of their unborn baby, reported Contactmusic.
"It's a girl. I'm very, very excited about becoming a daddy. I can't wait. The missus is, like, 'Don't go telling,' and I said, 'I won't. My life is amazing right now. It's fantastic, you know," he said.
The 38-year-old singer is already planning to teach his daughter self-defence in order to keep her safe when she is older.
"I'm going to teach her football and karate and boxing. That's the first thing she's going to learn to keep people like me and best friend Johnny Wilkes away," he added.
