Peter Andre, 40, and girlfriend Emily MacDonagh, 23, are preparing to welcome their first child into world just one year into their romance and are said to be "absolutely thrilled".
The new addition to the family is set to arrive just months after Peter's ex-wife Katie Price is due to give birth to her fourth child - her first with third husband Kieran Hayler.
A source told a daily newspaper: "Peter and Emily are over the moon. They absolutely adore each other, so having a baby together feels completely natural.
"As far as they are concerned they are going to spend the rest of their lives together and will definitely get married in the next year or so."
The I'm A Celebrity… Get Me Out Of Here star met his young Bristol University graduate through her dad - a surgeon who operated on Peter back in 2010 when he had kidney stones.
According to the insider, Emily has just finished her degree and hopes to follow in her father's footsteps to become a doctor, so is "unlikely to be a stay at home mum."
Peter already has Junior, eight, and six-year-old daughter Princess with Katie.
