The 52-year-old broadcaster made the announcement during his BBC Radio 2 show earlier today (16.02.18), revealing Natasha has managed to conceive after undergoing IVF treatment.

Speaking on his morning programme, Chris explained: "Mrs Evans is, she is. Double trouble, twin turbo. We have known for a while, obviously. She is definitely the mother, no doubt about that."

The veteran star - who was previously married to fellow broadcaster Carol McGiffin and pop star-turned-actress Billie Piper - revealed he'd already tried to break the happy news to their five-year-old son Eli, saying he "has got a shock and a half coming, he's got a double shock coming".

Chris subsequently shared: "We tried to tell him, he doesn't quite get it yet. Eli is mum's best mate. That is going to change, my friend."

Chris' baby news was also announced on Radio 2's official Twitter page.

Chris and Natasha are already parents to a nine-year-old son called Noah, while the former 'Top Gear' presenter has a 32-year-old daughter, Jade, from his previous relationship with Alison Ward.

Jade gave birth to her first son Teddy back in 2015, and the baby's grandfather was quick to congratulate her on the arrival of her child.

Chris shared a photo of Teddy on Twitter, captioning the image: "Teddy Rupert is here!! Everyone is doing brilliantly. Congrats to Ma & Pa, Alison and Wardy, Sandra and Gavin. (sic)"
