The Scarlets fan was left red-faced after her furious reaction to a controversial decision was caught on live TV, with her sudden realisation priceless

A passionate Scarlets supporter has become an unlikely social media star after her furious reaction to a controversial refereeing decision was caught on live television during her side's defeat to the Bulls in South Africa.

The Welsh fan was watching on from the stands in Pretoria when the Scarlets were denied what would have been a crucial try in Saturday's United Rugby Championship clash, prompting an outburst that television cameras captured in all its glory.

With the visitors trailing 26-12, makeshift winger Archie Hughes produced a moment of individual brilliance, kicking ahead and racing after the ball before diving to ground it at virtually the same time as a Bulls defender.

After consulting the television match official, the referee ruled that the ball had been grounded simultaneously, meaning no try could be awarded.

It was a bitter pill to swallow for the Scarlets, who had seen another potential score from Gareth Davies chalked off just moments earlier for offside.

And one supporter in particular was clearly not impressed.

As the television cameras panned towards a woman wearing a Scarlets shirt in the crowd, she made her feelings abundantly clear about the decision.

"Bull****!" she declared furiously.

"Absolute rubbish!" she continued, seemingly unaware that her reaction was being broadcast to rugby fans watching around the world.

But the penny soon dropped.

Glancing up towards the big screen inside the stadium, the supporter suddenly realised she had been caught on camera, with her expression immediately changing from fury to amused embarrassment.

A sheepish grin spread across her face as she raised her hand to her mouth, seemingly recognising that her passionate outburst had just been shared with a rather larger audience than she had intended.

The hilarious moment was subsequently shared by South African broadcaster SuperSport Rugby, which posted the footage on X alongside the caption: "SuperSport's cameras are at it again."

The clip quickly attracted tens of thousands of views, with rugby supporters on both sides of the equator thoroughly enjoying the fan's reaction.

One Welsh supporter wrote: "Exactly what we all were thinking," accompanied by a laughing emoji.

Another added: "Loves a passionate Scarlets supporter."

South African fans were equally amused, with one joking: "How will she explain this to the church members tomorrow?!"

Meanwhile, one viewer was particularly impressed by the television director's impeccable timing, writing: "Kudos on focussing on the right person at the right time. Excellent camera work."

The incident provided a moment of light relief in what ultimately proved a difficult afternoon for the west Wales region.

Nigel Davies' side had endured a nightmare opening half-hour at Loftus Versfeld, falling 19-0 behind after tries from Jeandre Rudolph, Willie le Roux and Dylan Maart.

However, the Scarlets mounted an impressive fightback, with John McKee and Sam Lousi crossing before the interval to give the visitors renewed hope.

Davies then thought he had reduced the deficit further after a clever attacking move, only for his effort to be ruled out for offside.

The Bulls capitalised on that reprieve through Marcell Coetzee before Hughes was denied his spectacular solo effort following the TMO review, sparking the now-viral reaction in the stands.

Despite those frustrations, the Scarlets refused to lie down.

Hughes eventually got his name on the scoresheet after Bulls centre Stedman Gans was sent to the sin-bin, before Joe Roberts crossed to complete a remarkable comeback and bring the scores level at 26-26.

But the visitors' resistance crumbled in the final quarter as the Bulls ran in 28 unanswered points to secure a comprehensive 54-26 victory.

Coetzee completed his double, while Sebastian de Klerk, Johan Grobbelaar and Maart also crossed as the hosts pulled away.

The Scarlets at least returned home with a four-try bonus point, although the result left plenty of frustration following a contest in which they had battled their way back from a seemingly hopeless position.

And for one travelling supporter, it was certainly an afternoon she is unlikely to forget in a hurry.
