Alex Jones made the surprise announcement on The One Show that she is pregnant with her third child.
The TV presenter revealed live on Thursday’s programme that she and insurance broker husband Charlie Thomson are expecting a baby girl.
After her co-host Ronan Keating made a quip about ‘lockdown babies’ and asked if she had anything she wanted to say, Alex, 43, made the big reveal.
She said: ‘I feel really nervous all of a sudden. It just seems like a good time to share some news with everybody, and the crew in the studio for the first time.
‘I mean lockdown has been anything but predictable and we’ve had some really unexpected news – baby number three is on the way.’
Turning to Ronan, who welcomed daughter Coco last year, she added: ‘I need all the tips. We didn’t see that one coming but we’re delighted.’
When the Boyzone star asked if she was having a boy or a girl, Alex said: ‘A little girl’ as the studio applauded.
Ronan said he was ‘so excited’ for the couple, saying: ‘Congratulations. Lovely.’
Alex and Charlie are already parents to sons Teddy and Kit, who was born in 2019.
The One Show airs weekdays at 7pm on BBC One.
