The Good Morning Britain presenter stepped out in a gorgeous red frock at a telly bash on Wednesday (October 1), looking positively blooming as she smiled for the cameras and played with her bump.
Charlotte, 39, who is expecting her first child with husband Mark Herbert, chose a Tiffany Rose maternity dress for Lorraine Kelly's anniversary do, teaming the fancy red number with killer heels.
Bet they were kicked off the minute she got inside!
Charlotte revealed her happy news live on Good Morning Britain (not that they needed the ratings boost or anything...), following the announcement up with the cute Tweet:
"I'm delighted to announce some breaking news of my own on @gmb this morning - I'm pregnant! Big thanks for all the lovely messages xx"
The presenter recently met fellow mum-to-be Rosamund Pike, who dropped by Good Morning Britain to talk about her new movie, Gone Girl (and have a bump off with Char).
Rosamund won on the bump front as she is nearing the due date of her second child. Charlotte has a little longer to go - she is rumoured to be due in February next year.
