Peter Andre's wife thinks raising a child is ''hard work''.

The 'Mysterious Girl' singer's new spouse Emily would like to have another child with him one day, but for the moment she is focused on her career as a doctor and their 18-month-old daughter Amelia.

She said: ''I don't want to work for years before I have another baby, but I want to get working and get in the system.

''I don't think I'd like to have more than one more.

''I love Millie to bits, but there's no doubt it's hard work and, given how busy I am with her, I don't want to space my time too thinly between lots of children.

''Although if the next baby is as brilliant and well-behaved as her, then I probably would have another.''

But Peter - who also has children Junior, nine, and Princess, seven, with ex-wife Katie Price - is keen for them to expand their family again.

He said ''I thought I only wanted one child with Emily, but I'd be really happy with one more.''

The couple tied the knot earlier this month and couldn't be happier.

Peter gushed to OK! magazine: ''I've married the love of my life. We really couldn't be any happier.''
