The 35-year-old presenter from Melbourne revealed the good news live on air during her radio show, Fifi and Jules, on Monday.

“It’s the most amazing thing that’s ever happened to me. Look out, there’s another Box coming into the world!” a delighted Fifi said.

Fifi, who maintains she has always wanted a family, also wrote a statement on the website fifiandjules.com saying that she felt there was always something missing in her life.

“I have been blessed throughout my life and loved every twist and turn in my journey, but despite the happiness I have experienced with career and friendships, there has always been something missing,” she wrote.

“Like many women in their thirties I was starting to wonder if it had come at a cost, and for me it was the greatest cost because, despite loving my life, nothing could replace what I truly wanted more than anything - to be a mother."

Fifi, who has made no secret of being unlucky in love, says she began seeing someone at the end of last year who wishes to remain out of the public eye. The pair say they are committed to bringing a happy, healthy baby into the world.
