Radio One DJ Sara Cox is expecting her third child, she has announced.
"How terribly modern of me to say this on Twitter! Wanna share with you just before I do it live on air: I'm pregnant and over the moon xxx," the mum-of-two told fans through the social networking page.
She later told listeners of her radio show that she and partner Ben Cyzer were "beside themselves with happiness".
Ben is stepdad to Sara's daughter Lola, 4, and father to their one-year-old son, Issac.
And the 34-year-old has no intention of giving up her job to become a full-time mum.
"I'd go stir crazy if I didn't work," she says.
"Work and being a mum go quite nicely hand in hand. Each needs the other to keep me sane." says Sara, pictured leaving the Radio One studios after sharing her happy news.
