From grappling with pigs and tractors to good-natured squabbling with his boss Jeremy Clarkson, Kaleb Cooper was undoubtedly the breakout star of Clarkson's Farm.
But as its fourth series got under way on Friday, viewers of the hugely popular Prime Video show learnt that there's an unlikely new Diddly Squat farmhand in town - a TikTok star called Harriet Cowan, who is also a full-time nurse.
These pictures show 24-year-old Ms Cowan arriving for work at her hospital in Derbyshire this week, 100 miles from the farm in Chipping Norton.
Dressed in her smart blue uniform with a navy cardigan and NHS lanyard, and getting out of a pristine white SUV, her day job is a world away from the boggy fields and hedgerows of Diddly Squat.
But just like her predecessor Mr Cooper, she is more than qualified to help Clarkson run the 1,000-acre farm he bought in 2008.
As a farmer's daughter, she has broadcast her extensive agricultural skills to her 38,000 followers on the video-sharing app - from driving tractors to planting fields and tending to the animals.
On Friday's show, viewers were surprised to learn that 26-year-old Mr Cooper, Clarkson's farm manager, would not be appearing in several episodes of the series after a tour for his one-man show clashed with filming.
It leaves Clarkson running the farm on his own, and sees him hiring a freelance contractor - Ms Cowan - to help.
Perfectly groomed with impeccable make-up and false eyelashes, blonde Ms Cowan nonchalantly claims she's 'never seen' the show.
But she wastes no time getting stuck in, proving to be a dab agricultural hand. She fences a pig pen, plants barley in the fields, spreads fertiliser, trims the hedges - and even makes an attempt to trim Clarkson's unruly eyebrows.
She also supplies him with no end of common-sense advice and fixes his tractor.

It all prompts Clarkson to remark: ‘Those eyelashes, and what she’s doing, don’t necessarily go together do they?’
She is likely to prove more than a match for the venerable Clarkson.
At one point, as he gives her a tour of the site, which includes a 4,000-year-old Neolithic fort, she quips: ‘Nearly as old as you?’
And she causes him visible irritation when he tells her Mr Cooper is on tour and is famous ‘like Julian Clary or Lenny Henry’—and she claims she has no idea who they are. Clarkson goes on to praise her for being ‘a star’ and ‘completely brilliant’ thanks to her farming knowledge.
Ms Cowan (pictured) also supplies Jeremy Clarke with no end of common-sense advice and fixes his tractor in Friday’s episode.
Harriet, whose father runs her family farm and whose mother is also a nurse, has a nursing degree from the University of Derby.
The young TikTok star has also been a leading voice in the young farmer's movement and has used her social media following to campaign against Labour's changes to inheritance tax rules for family farms.

Clarkson's Farm has become one of the most watched series in the UK on Prime Video, and has been praised for raising the profile of British farming.
It has also launched Mr Cooper's career. He was already working on the land when Clarkson bought it, and has now written three books.
It seems that Ms Cowan, too, may well follow suit.
