On the latest series of Clarkson's Farm, which follows TV icon Jeremy Clarkson, the former Top Gear presenter invited bird enthusiast Hannah Bourne-Taylor over to help him identify the birds living on his farm.
Hannah quickly became a fan favourite, as many were amazed by her incredible knowledge of all kinds of birds and how quickly she could identify them just by their sounds.
Since the series came to an end, Hannah has continued to educate her now 239,000 Instagram followers on various bird facts, including how to care for them during the record-breaking summer heatwave.
But recently, fans have been floored after learning how old Hannah is, as she was seen celebrating her recent birthday over the weekend. But in true Hannah fashion, she decided to hint at her age by comparing it to the ages of various bird breeds.
In the post, Hannah shared: "It's my birthday, so to celebrate being alive, I'm going to talk about bird ages."
She explained that crows live for up to 20 years, while most garden birds, like blackbirds and robins, only live for about five years.
"My favourite bird was swift, the oldest in record was 22 which is an incredible life if you think about it," she added, before revealing 'the winner' was the albatross who typically live between 30 and 60 years in the wild. To this, Hannah claimed they are "a lot older" than her.
So how old is Hannah? In another post dated a day prior, she revealed she was in her thirties 'for a few more hours', leaving many baffled.
On the day of her birthday, (September 12), Hannah shared a clip where she was dared to put her face in birthday cake, something she went on to do without hesitation, earning herself laughter from people behind the camera.
Wearing a short, red dress, Hannah climbed up on the kitchen counter before pressing her face into the cake and bursting into laughter. She was later seen digging into the cake, still with frosting all over her face.
People quickly took to the comment section to share their birthday wishes, as many were floored to learn the TV star had entered her forties.
"Happy cake smash Hannah! No way you’re 40!" one baffled fan commented.
"Surely not 40 years of age," someone else wondered.
"Happy birthday! I cannot believe you’re 40!! I’m guessing you have an awful painting in your attic," another person wrote, jokingly referencing to the Picture of Dorian Grey, where the painting of the named character ages rather than the character himself.
Someone else commented: "I’m sorry, you’re 40?! I literally don’t believe that comment. I’m absolutely astounded. I thought you were about 25! What the f**k! Happy birthday!"
However, not everyone was impressed by her cake smashing, as one wrote: "Ruined a perfectly good cake!" To this, one of Hannah's relatives replied: "No she did NOT. It tasted great lol."
