Sonia Kruger has revealed that she used a donor egg from a close friend to fall pregnant with her first child at nearly 50.
The Nine Network TV presenter announced her big news on Twitter over the weekend with a cute pic of her own feet in sexy Valentino shoes alongside a pair of baby socks.
"Hey everyone. Here's a fun fact...I'm having a baby!" she posted.
Kruger and her partner TV executive Craig McPherson have previously revealed their efforts to fall pregnant both naturally and through IVF.
And speaking on Nine's Mornings show on Monday, the Big Brother presenter explained to Richard Wilkins that a close friend had donated the successful egg.
"I wanted to be really clear today on the show with our viewers and let everybody know that I did go through IVF and I did have an egg donor," said Kruger, who turns 49 on Thursday.
"When you get to my age, to use your own eggs to have a baby, you're not really going to be successful - I mean the odds are sort of one in a million, and my doctors have been very clear with me because I've been through IVF before.
"So I have a very good friend who basically gave me an egg and that's how this pregnancy came about."
Kruger, who is due next February, said she is "thrilled to bits" and felt incredibly appreciative towards her friend for what she did.
"I think it's entirely possible to be as in love with a baby that doesn't necessarily share your DNA, as it is when you adopt a child and you fall in love with that child," she said.
But the first 16 weeks were still a "knife edge" of nerves as she fought off feelings of paranoia that came from her previous IVF miscarriages.
"I saw a heartbeat, which I had never seen before, that was incredible," she said.
"(Then) I became paranoid, convinced I would go for the next scan and there would be no heartbeat.
"There's still a long way to go but fingers crossed."
Kruger has also told The Australian Women's Weekly magazine that the couple know the sex of their impending bundle of joy.
