This week, Prime Video unveiled a trailer teasing the upcoming season of the show.

In response, Jeremy recruits a new farmhand who proves to be just as amusing as Kaleb, reports .

Let's introduce Harriet Cowan, the newest member of Clarkson's Farm.

So, who is Harriet Cowan, the new assistant on Clarkson's Farm?

Harriet, aged 24, recently posted the trailer on her Instagram account, captioning it: "Ekkkk something exciting is coming on the 23rd of may #clarksonsfarm @primevideouk [sic]."

After much speculation, she has been confirmed as a full-time nurse and farmer, frequently posting updates from her work.

In March of this year, Harriet shared a charming collection of photos from her work on a farm.

She captioned the images: "A very farmy week prepping for spring and new babies good things to come this spring #farm #farming #agri #cows #bordercollie #sheepdog #country #countryside #farmgirl [sic]."

From her social media posts, it's evident she's quite taken with the agriculturally inspired sock retailer Country Moos, often showcasing her latest buys and having scored a promotional partnership with the brand.

The trailer for Clarkson's Farm reveals that Harriet was unaware of the TV series when Jeremy Clarkson hired her.

Thrown into farm life, Harriet took to it like a duck to water at Diddly Squat Farm, pitching in with tasks from feeding animals to erecting fences and showcasing some serious welding skills - skills noted by Prime Video as pivotal in bringing Diddly Squat up to speed astonishingly quickly.

She is said to be dating fellow farmer James, as reported by the Daily Mai. She previously shared snaps on social media of them.

Harriet, a farm girl since childhood thanks to dad Eddy's tutelage, has the countryside running through her veins, which shows in her robust farming prowess.

An intriguing aspect of her life's tapestry: she pursued dual vocations as a nurse and a farmer to honour both of her parents' wishes-her mum's nursing aspirations for her and her dad's farming legacy.

TikTok fame isn't far behind either; Harriet enjoys an avid fan base of roughly 35,000 followers, where she engages them with regular updates.

During her time training as a student nurse, Harriet, alongside pals, brought some light-hearted relief to NHS workers amidst the coronavirus mayhem with a viral challenge, echoing her sentiment to about rallying spirit during club shutdowns due to the pandemic: "I thought we should do something to get everybody together as our club isn't meeting because of coronavirus."

Harriet is set to be thrust further into the limelight on Clarkson's Farm, as viewers will witness her handling the famously disorderly Diddly Squat Farm.
