Peter Andre and Emily MacDonagh haven't ruled out expanding their brood once more.

The 44-year-old singer and his wife already have Amelia, four, and 14-month-old Theo together, but they have admitted they aren't quite finished with their family just yet, as they are considering having a third child together, although Emily admits she wouldn't want to get pregnant now, as she's busy with work.

She told OK! Magazine: ''We have a lovely relationship and I'd actually say we're closer than ever. I did have a bit of a moment the other day. A lady told she was in the very early stages of pregnancy and she hadn't told anyone else and I had a little moment where I felt a bit jealous. When you're pregnant it's so special and everyone wants to talk you to you about it and you have that amazing feeling of growing a person inside you. It's absolute magic. It just brought back all these feelings for me. I worry it's going to become more often now I've thought it once. So I'm not saying I'd have one right this second as I need to work, but I'm not ruling it out.''

Meanwhile, Peter - who also has Junior, 12, and 10-year-old Princess with ex-wife Katie Price - recently admitted his two older children are very ''adaptable'' when it comes to the changes in house rules between his home, and their mother's home.

When asked if his children with Katie find it difficult dealing with their different house rules, he said: ''Yes and no. Kids are very adaptable. My mum was really loving and I knew there were things I could get away with in front of my mum and things I couldn't with my dad.''

One rule the 'Mysterious Girl' hitmaker insists the whole family stick to is only to use ''one screen'' at a time, so mobile devices and tablets are banned when they're watching TV together.

He said: ''In our house, we have a one screen rule. If the TV is on, we are all watching TV without any other screens and that includes me and Emily. You have to lead by example.''
