A recent picture of her in a flowing dress, holding her back in an awkward posture seemed to give the game away.
And now Zoe Ball has confirmed to listeners of her BBC Radio 2 show that she's expecting again.
"I've got some lovely news for you all actually. I'm having a baby," said the bubbly blonde, who is married to DJ Norman Cook.
Zoe, 38, added that she'd been rather "green of gills" lately and was "eating everything in sight".
The couple, who have an eight-year-old son named Woody, have recently come through a difficult spell.
In March Norman – aka Fat Boy Slim – checked himself into rehab to seek help for alcohol addiction.
