You’ve got to feel sorry for The Voice’s producers at the moment. Viewing figures for the talent show have almost halved since its peak in the Blind Auditions, the programme was beset with technical problems last week - and as if all that wasn’t enough, they’ve reportedly got a troublesome Jessie J to deal with too.

So what's going on with the artist formerly known as Jessica Cornish?

It seems that barely a day goes by without a story appearing in the papers about Jessie trashing the show, and only this weekend she apparently scuppered Sunday’s results show by tweeting a picture of her two remaining semi-finalists hours before it aired.

A BBC insider is reported to have explained Jessie's tweet as an accident, saying: "It was an innocent mistake, and obviously everyone will have to be more careful in the future." But mistake or not, it's quite a serious blunder, and one which may have put fans on Twitter off watching the show.

And this rogue tweet is the latest bit of seemingly odd behaviour from Jessie, who, if the tabloids are to be believed (and they frequently aren't), is making it her mission to enrage The Voice’s top brass. 

Earlier this month she caused a storm after she was quoted as saying she doesn’t watch the show and criticised its producers’ handling of the wardrobe in the Blind Auditions, saying, “It was lame and not thought through.”

A week later she was back in the headlines after allegedly snubbing BBC1 controller Danny Cohen after a taping, leaving him standing "like a lemon", according to reports.

And rumours abound about her backstage behaviour, which has been painted as diva-ish in the extreme. “She has been late arriving to rehearsals and filming sessions,” “she’s very demanding and always arrives with an entourage of managers and assistants,” and “Jessie is getting far too big for her boots” are just some of the quotes directed her way in recent times.

However Jessie claims to have been stitched up by the press and responded to the reports about her allegedly bad attitude by tweeting: "I don't know what shocks me more that the papers get away with the lies they print or how many people believe it."

Interestingly, despite all the controversy, she's also consistently been supported by those closest to the BBC talent show. Danny Cohen says that he “loves” all the show’s coaches “in multiple ways”; Voice coach Tom Jones recently revealed that he’d be happy doing a second series alongside Jessie and Holly Willoughby has dismissed her critics, insisting that Jessie is just a “strong woman.” 

She's also apparently been offered £400,000 - double her currently salary - to appear on the second series of The Voice, which if true surely counts as a ringing endorsement from the BBC.

All of which makes the errant tweet and the all these off-colour articles about Jessie that much harder to understand. After all, Jessie is not stupid, and she has a big enough management team. Someone in her camp must have realised that her extreme candour in interviews and her leaking of the show's results would leave her wide open to criticism.

So what exactly is going on? Is Jessie trying to cultivate a personality as an opinionated loose cannon, or is she just displaying the typical over-confidence of many 23-year-olds? Is she trying to distance herself from an ailing TV format, or is Jessie the victim of a media smear campaign?
