X-Factor star Diana Vickers has been branded "disrespectful" after posting a video about Queen Camilla and Princess Diana hours before the Coronation.
The 2008 semi-finalist, 31, shared a clip of herself and podcast pal Chiara Hunter singing about the royals.
The two friends don plastic crowns in the clip, whilst they joke about King Charles' relationship with both Camilla and Diana.
Posting on both of their Instagram accounts, they captioned their video: "QUEEN CAMILLA ( the ultimate long game) For all you side pieces out there… stay focused."
The duo, known to fans as Ki and Dee, shared their made-up song but were met with backlash in the comments.
They started their video by singing: "Ladies, this is a lesson for all of you side pieces out there, stay focused.
"Well there was three of us in this marriage," Princess Diana's voice can be heard in an overlay from her infamous interview.
"But only one can be Queen - Camilla," the pair sang in fake American accents.
They then begin singing about Camilla and Charles' secret love affair, claiming they "were always destined for each other's heart".
"And Diana said 'Love me love me love me' I want to work on this marriage, and Charles was like 'ABSOLUTELY NOT' and we know what happened in Paris...
"Chemistry is chemistry, love is love, kept apart by an institution they said CHARLES SHE'S NOT ENOUGH - a little side piece divorcee, said she couldn't be Queen but she's doing it anyway", they continued.
When the pals get to the chorus they sing: "Coz ladies persistence is everything, C-A-M-I-L-L-A - what does it spell? Winner.
"C-A-M-I-L-L-A - what does it spell? Inspiration".
The two-minute song, shocked viewers as they flashed up images of Princess Diana in her iconic revenge dress with "waste of time" scrawled over it.
It wasn't long before royal fans took to the comments to hit out at the singer.
"I don't get why this is funny... I find it disrespectful," wrote one.
Another added: "The lengths you’re willing to go to for a viral moment."
A disgruntled viewer snapped: "You have some nerve !!"
"I can’t actually process the evil Diana Vickers posting this. What possessed the 31-year-old to do this," quipped another.
Someone else added: "Now what in the world is Diana Vickers on?!? She was one of my faves from X-Factor…what a pity."
"The tory Diana Vickers has truly made a fool of herself with this abysmal nonsense she now churns out in hopes of some kind of comedic career. Evil and awful. She really did fool us once with her phoney act," remarked a user.
Diana replied to one of the comments which called her an "evil sad little girl" on her Instagram story, by writing: "Happy Friday x".
She later snapped a pic of herself which she commented: "The most hilarious thing I've heard all week that I'm a Tory. As you were."
