Swan in shock over second pregnancy
The Australian television star, who is best known for presenting chatshow The Circle, announced her news on the show over the weekend.
Swan, who put on nearly 50kg during her first pregnancy, recently lost a lot of weight hoping that it would boost her fertility.
Swan told Woman's Day magazine: "It's worked! I can't believe how quickly it's happened! I started trying to calculate my cycle. I waited for the first day of my second period, and 28 days came and went. It got to 47 days, and I'm thinking, 'This is very unusual'.
"Finally [I did a pregnancy test] and there was a really faint line on the strip and I thought, 'Oh my goodness'."
