In an interview with new! magazine, when asked whether he would try for another baby, he said: "When we're married, yeah! I can't wait to try for that!"
Andre is already dad to Junior, nine and Princess, seven with former wife, Katie Price, and 16-month-old Amelia with his current fiancee, MacDonagh.
With two daughters and one son, the Mysterious Girl singer said he was not bothered whether he had a girl or boy, although he did say that he had initially wanted a boy when MacDonagh was pregnant with Amelia.
He said in the interview: "I wasn't gutted – I was happy – but I've fallen so in love with her that I'd happily have another girl."
MacDonagh gave birth to Amelia, on 7 January this year.
However since the birth, the couple have kept their life quite private, sharing few photos of baby Amelia.
Weeks after they introduced their newborn to the world, Andre got down on one knee and proposed.
Speaking of the engagement, Andre told OK! Magazine: "She just said 'Are you serious?' and burst into tears – it was so emotional. We lay down in the nursery for ages because it was such a special room to us."
The couple intended to wed this year, but Andre said they have had to delay the wedding because of work reasons.
MacDonagh was studying for a medicine degree when she met Andre, and has recently qualified as a doctor.
