The 39-year-old 'Mysterious Girl' hitmaker is already a father to five-year-old Princess Tiaamii and seven-year-old Junior, who he had with ex-wife Katie Price, reported Showbizspy.
Asked whether he wants another baby, he said, "Yes. In the future yes. But will only commit to marriage again if it will be forever."
Andre has been dating Australian student MacDonagh for over four months and has known her since her father Ruaraidh, a urology consultant, performed surgery on him two years ago.
He is determined to take things slow this time around after his previous marriage to Price ended after three and a half years in 2009.
"I won't rush into it. There is an old saying, 'Marry in haste, repent as leisure.' It is true you marry quick and ... well, sometimes it works for people.
"I still believe in the constitution of marriage, as long as your intention is to stay together forever. I want to be careful, that is all. I only ever wanted to be married once in my life," he said.
