She'd only given birth three months ago, but TVNZ reporter Tim Wilson says he knew his wife was pregnant again by the glint in her eye.

Wilson, 50, says he and his wife Rachel, 30, were driving to Tauranga with their three-month-old Roman in the middle of last year when he had a hunch she might be pregnant again.

"I looked over and noticed her eyes. They were blazingly white, just like they were with Roman, and I thought, 'She's pregnant'," Wilson, a reporter for Seven Sharp and Newstalk ZB host, tells Woman's Day.


He was right and Rachel's due date for "Truffle" - the nickname they've given their unborn baby - is February 27, just five days before the first birthday of Roman, the couple's first child together.

Despite the pregnancy surprise, the couple say they'd love a large family.

"We'd like four or five kids and people's jaws drop when we say that," Wilson tells WD.

The pair also discuss their 20-year age gap in the interview.

"I guess you could say Rachel is more grown-up than your average 30-year-old, and I am more immature than the average 50-year-old. We don't really notice it," Wilson says.
