It's been a year and a half since we first learned that Blake Shelton and Gwen Stefani are dating, and unlike most workplace romances, the relationship seems to have had only positive impacts on the singers' careers.
The Voice viewers appear to enjoy the Gwen-Blake dynamic, and ratings for the show continue to surge.
So what's the problem?
Whenever co-workers date, the situation is always fraught with peril, and this one - albeit only after a long honeymoon period - is proving to be no exception.
It looks as though audiences and producers of The Voice may soon find themselves wishing Shelton and Stefani had never hooked up in the first place.
Sources close to the singing competition say Gwen is ready to leave her her coaching duties behind.
The problem, it seems, is that Miley Cyrus plans to return to The Voice next season, and Gwen is less than thrilled by that development.
From the time of her first appearance on the show, there were rumors that Miley didn't get along with her co-stars.
Most of the reports involved a feud between Miley and Adam Levine, but it seems Cyrus also rubs Stefani the wrong way.
Gwen and Miley have never appeared on the show together (Miley served as Gwen's temporary replacement in 2016).
According to sources close to the popular NBC singing competition, which debuted in 2011, Gwen intends to keep it that way.
Insiders say Gwen has made it perfectly clear to her bosses that The Voice Season 12 will feature either Stefani or Cyrus - not both.
“Since Miley is set on coming back to the show next season, Gwen definitely does not want to be on the panel alongside her,” says one tipster.
So what does all of this have to do with Blake Shelton?
Well, it seems that The Voice producers aren't the only ones receiving ultimatums from Gwen these days.
Sources have indicated that if the former No Doubt front-woman doesn't come back to the show, Blake won't be returning either:
"Since Gwen does not want to return, now Blake is considering throwing in the towel as well," one insider claims.
The show has been a consistent hit for NBC since its inception, but producers now fear that Miley-gate could bring it all crashing down:
“Producers feel like it might be a domino effect,” said one source when asked about the possibility of other coaches quitting as well.
We guess this time Miley really did come in like a wrecking ball.
UPDATE: Another source close to the situation is also claiming that Stefani refuses to work with Miley Cyrus, but for a different reason.
Slightly different, in that there is no specific reason.
Apparently, there's no bad blood, as the duo has never worked on the show together, but Miley's feud with Adam Levine worries Gwen.
Stefani believes she simply wouldn't get along with Cyrus, which in turn has Blake considering other options and producers very concerned.
Says the insider regarding the backstage drama:
“Producers would love nothing more than for both Gwen and Miley to be on the show at the same time because there would be so much drama."
They would love that, in a perfect world, however:
"Gwen simply does not want any part of it."
“They would even throw [Gwen] a considerable amount of money, but between her and Blake [Shelton], money really doesn’t matter.”
Okay, let's not get too carried away here. We're sure finances do matter to some degree, especially if there's no real beef with Cyrus.
There's a price point for everything, and everything is negotiable. Moreover, there's a shelf life for anyone in show business.
You have to strike while they still want you, right?
We're also that guessing if Gwen Stefani is pregnant, which is being widely reported, that this development might impact things as well.
Stay tuned, because the plot? Thickening.
