Talking to Mother & Baby magazine, Pete said: 'I'd be happy with one more,' adding that: 'I'd love a boy next - I wanted a boy this time but now that I've got a girl she's just everything so it doesn't matter what you want because when they're there it's great isn't it?'
Pete already has two children, Junior, 8, and Princess, 6, with ex-wife Katie Price.
The doting father was also quick to heap praise on new mum Emily, 24, who he described as 'a brilliant mother - I watch her and I just go wow, she's a natural.'
And according to Pete, 41, his daughter Princess is 'absolutely obsessed' with her new little sister Amelia, and even had a say in the naming process.
The family are preparing to be separated come Autumn, when the singer will go on tour and Emily will resume her medical degree whilst living back with her parents in Somerset.
Emily had been studying at the University of Bristol before falling pregnant with Amelia last year. She apparently deferred the last year of her course in order to have her.
