Viewers of Good Morning Britain were left astounded on Friday as the show took a pause to celebrate a memorable milestone for one of their presenters.

During the broadcast, hosts Adil Ray and stopped everything for a special bulletin. Kate excitedly announced: "Now, we do have some major breaking news about someone in this very studio."

Kate then stunned viewers by revealing that it was none other than Charlotte Hawkins' birthday, saying she was born this day back in 1975.

As she showered praise on her colleague, viewers were treated to nostalgic photos of Charlotte's youth, including images of her with a teddy bear and beaming on horseback, with an amused Charlotte exclaiming: "Where did you get these from?!"

Humorously pointing out her family's 'betrayal', Kate chuckled at how they had sent in the snaps.

But it was an old video from early in Charlotte's career that really caught Adil off-guard, leading him to jest: "What on earth? ! You look older there! You look 63!".

Charlotte couldn't help but laugh, confessing her attempts to look more 'mature' back then. The festive mood continued as Laura Tobin rolled in with a birthday cake trolley, right before Adil handed over a beautiful bouquet of flowers, reports .

As the celebrations drew to a close, Charlotte shared that her daughter keeps reminding her of turning half a century.

Kate Garraway was taken aback by a black and white picture of her colleague from younger years, mistakenly asking if it featured Marilyn Monroe, only for Charlotte to respond: "No, that was me back in the day, believe it or not!

"That was in my modelling days when I was earning a bit of money, while I was at university."

To which Kate exclaimed: "Happy Birthday, Charlotte. I still can't quite believe she's 50. I think it's a lie."

Viewers rapidly flocked to to echo Kate's astonishment, with many finding it hard to grasp that Charlotte is 50.

One viewer commented: "Happy birthday Charlotte, you can see what a beautiful person you are inside and out 50? I will take some of what you are having."

Another chimed in with: "Doesn't look anywhere near 50."

A third person gushed: "Happy 50th Birthday, Charlotte [sic] Are you sure? You look amazing. Enjoy your day."

Likewise, someone else tweeted: "@ Happy Birthday to the lovely @CharlotteHawkns, I hope she has a lovely day and you don't look a day over 40."

In concurrence, another fan remarked: "Happy birthday, I thought you were in your mid 30s."
