"CERYS is a nymph. She's a fairy. Cerys is luminous - everything about her is angelic."

No, not the words of besotted fellow I'm A Celebrity Get Me Out Of Here! contestant Marc Bannerman but of co-jungler, bonkers bint and (usually) queen of the killer put-down Janice Dickinson.

Yes, the 38-year-old Welsh songbird has surprised everyone and is giving what amounts to a masterclass in flirting among the faux ferns and while the object of her attention, Bannerman (AKA Gianni off EastEnders), doesn't stand a snowball's chance in hell, judging by Dickinson's remarks and those of others in this year's show, it's not just him who has fallen hopelessly in love with her.

So what is Cerys's secret?

Well, the girl is just fabulous at flirting, which mainly amounts to making people feel special. She smiles at everyone, looks utterly fascinated when they tell her about their ingrown toenails and looks suitably sympathetic when they bleat about their bunged-up bowels.

And while the other females of the species stomp about the place like camp commandants, Cerys flits around like a wee pixie, dropping feather-soft touches on Bannerman's strong shoulders; while the other girls shout and compare their fake boobs, she sings gospel like an angel; and as everyone else gradually grows more and more dishevelled and smelly, she appears radiant, like some roaring twenties movie starlet with her fresh-as-a-daisy skin and cute little bob.

They are all putty in her baby-soft hands, but Bannermen ("She makes my heart crumble") is particularly susceptible, mooning over her like a lovesick teen, despite knowing that his girlfriend will be watching every moment. Fists and teeth clenched.

In fact, said girlfriend, Sarah Matravers has now flown out to Australia and, let's just say, she aint happy. Luckily for Bannerman that means she missed Monday night's show where he and Cerys lay entwined in a hammock singing Lola to one another. Unluckily for him, all Sarah's pals' back in the UK phoned her to tell her all about it.

Now she finds herself in the extremely tricky position of humiliated girlfriend', where one minute she's threatening to cut up his clothes in revenge and the next she's promising to stand by her man (just in case he wins, which could help make her famous/richer/Kerry Katona's co-star of the next series of Iceland adverts).

But Sarah needs to cast her mind back to the circumstances of how she and Bannerman got together - on the set of Footballers' Wives Extra, while they both had partners, who, one assumes were ceremoniously dumped?

At least Cerys (who has recently got divorced) was up-front about her intentions, saying that she was going into the jungle to be like a sort of Jane who was "looking for her Tarzan".

It has come as a surprise to many people that this softly-spoken Welsh lass (who most of them have never heard of) should turn out to be such a ferocious man-eater; that the shy girl who looks like she wouldn't say boo' to a goose should openly court the attentions of a man who is already spoken-for.

Little would anyone have guessed that when she sang it's all over the front page' with her band Catatonia, almost ten years later life would imitate art and she would indeed be all over the front pages, and not because of her singing skills but her flirting ones.

In fact, there's a saying I love that could have been made for Cerys: Quiet pigs eat most grain.
