Julia Bradbury, who has a 3-year-old son named Zephyrus with partner Gerard Cunningham, revealed that she is due to give birth next spring.
And, after going through five rounds of IVF to fall pregnant, it's easy to see why the former Countryfile host is so excited about the news.
She told Hello! Magazine: "I'm completely overjoyed. The prospect of having two for one is just incredible.
"Starting later in life having children, I didn't ever think I'd have a big family.
"Zeph was the unexpected miracle and I was thrilled and happy to have him. It's taken a long time to get to this stage so the prospect of going from one to three is utterly amazing."
Admitting that she is concerned about being pregnant later in life, Julia said she is being cautious, insisting: "I am slightly guarded and I'm not taking anything for granted.
"This whole process is very much about milestones - getting to the next stage - so it's quite a rollercoaster.
"We've got to be ultra, ultra careful, really cautious and try to stay as healthy, calm and comfortable as possible."
The Countryfile beauty added that she was 'gobsmacked' to discover she was expecting twins, saying: "It's not an impossibility when you go through IVF.
"But when we found out at the first scan, we were gobsmacked. It was like 'Okay, deep breath'."
We can't wait to meet her little ones next spring.
