Good Morning Britain fans couldn't believe their after discovering weather forecaster Laura Tobin's age as she celebrated her birthday on the ITV show.
The presenter glowed today as she was presented with an incredible volcano cake by her co-stars.
Hosts Susanna Reid and Martin Lewis led the congratulations as they said: "Just want to say a very special happy birthday to Laura Tobin!"
As the classic Happy Birthday music played, Laura waved and grinned as the cake was brought in and she blew out the candles before explaining the reason behind her themed cake.
"Andi Peters today is going to be live from Mount Vesuvius and the competitions team said 'Would you like to join Andi Peters at Mount Vesuvius and I said, 'Yes! It's my birthday! This will be the best live ever!' And it basically got vetoed and it didn't happen, I'm obviously here, but instead I have a volcano cake! The next best thing!"
Susanna said: "Well, happy birthday! And Martin said he doesn't know how old you are - he guessed 24."
"Because I'm not stupid," he joked.
"Very, very close," she replied with a grin.
While she remained tight-lipped about her true age, viewers discovered that she was 41 - and they couldn't believe it.
One tweeted: "No chance @Lauratobin1 is 41 today. I thought you were mid 30s if that . #HappyBirthday #GMB."
While another commented: "So beautiful and stunning and Happy birthday Laura."
A third wrote: "#GMB Laura is 41 today then so she is."
