She already has the power to ruin entire weekends with a characteristic waft of her balletic arm.
Sian Lloyd is preparing for filming in Australia
She boasts an MP boyfriend - and she is about to burst onto TV screen in the second series of "I'm A Celebrity...Get Me Out Of Here!".
And if that wasn't enough, those of us watching television in south Wales are regularly rendered speechless as she swoons bizarrely over three-piece suites during an ad for a furniture store.
But if you thought that was the extent of Sian Lloyd's talents, well, you were wrong.
Now it seems, the "sunny demeanour and friendly smile" of one of Wales' most famous recent exports has inspired a new stage show - Melody: The Musical.
And the plot? Well, it goes something like this.
When she does the weather you are more interested in her than what's going on behind her
"It's about the nation's favourite weathergirl who is fired in the opening scene because she continually gets the weather wrong," explains composer Stuart Wood.
"Her outlook on life is somewhat optimistic, and she finds it difficult to see what reality is.
"She lives above a record shop and the guy who runs it is a DJ, who's completely in love with her, but she can't really meet his love."
Mr Wood - who says no venue has been confirmed for the show as yet - simply telephoned Ms Lloyd to ask if she would like to get involved in the early stages of the production, and she agreed.
"It was inspired by Sian's sunny demeanour and we thought she would be a great character for it," he added.
The weathergirl began working life at S4C
"When she does the weather you are more interested in her than what's going on behind her."
But however, interested Mr Wood may be, Sian Lloyd's heart is taken.
Her latest squeeze is Montgomery MP, Welsh Liberal Democrat leader and part-time harmonica maestro Lembit Opik.
In between pounding the corridors of power, he divides his time between fretting over asteroid collisions with earth, and his music.
Last year he released a single with the catchy title Hank MacGregor's Weekend Rock and Roll Band featuring Lembit Opik, which he had hoped would make Christmas number one.
Funnily enough, it didn't.
But enough of him - back to Sian.
Her star firmly in the ascendant, she is destined to reach even dizzier heights next week when the second series of " I'm A Celebrity Get Me Out Of Here!" gets underway.
The 'I'm A 'Celebrity' line-up
She has already left for Australia to prepare for the fly-on-the-wall extravaganza - which involves living in the outback for up to three weeks with nine other B-list celebs and a host of potentially fatal insects, snakes and plant life.
A world away from her old stomping ground of Maesteg, south Wales.
There she excelled at swimming and school, going onto get a first class honours degree in Welsh and a higher degree from Jesus College in Oxford, but she insists the Met Office college exams were the hardest thing she has ever had to do.
After college she began working as an S4C continuity announcer and presenter, before moving on, to become a weather presenter for LWT/Carlton, and then the ITV network.
The MP's hopes for a Christmas No 1 were dashed
Once voted TV's sexiest weather girl, she went on to become a founder member of the Social Welsh and Sexy (Sws) club for ex-pats living in London.
"She's so popular because she's been doing the showbiz thing for so long, she's good at it, works hard, and is larger than life," said actor and good friend Stiffyn Parry who founded Sws.
"She's one of those people you warm to, she's not part of a particular programme so she comes right out of people's TV screens into their living rooms."
That might be alarming in itself to some, but it would be the subsequent swooning over my sofa that would worry me...
