Diana Vickers is facing huge backlash for sharing a video of her singing mockingly about Princess Diana and Camilla Parker-Bowles, the Queen Consort.

The former X Factor star, 31, hosts a podcast with friend Chiara Hunter, and the duo branched out this week by creating an original song about King Charles and Queen Camilla’s affair, Princess Diana’s death, and essentially how Camilla ‘won’.

In the video, Vickers and Hunter wear crowns and sing to the camera, while images of Diana, Camilla and Charles flash up on the screen from time to time.

‘This is a lesson for all of you side pieces out there,’ they announced. ‘Stay focused.’

A clip of Princess Diana’s infamous BBC Panorama interview then plays, with the mother-of-two saying there were ‘three of us in this marriage.’

‘But only one could be queen – Camilla,’ they sing.

They go on to sing about ‘side piece divorcée’ Camilla and King Charles’ affair, and say Camilla had her ‘eyes on that money.’

Vickers and Hunter even appear to poke fun at the death of Princess Diana, singing ‘We all know what happened in Paris,’ and say Camilla ‘played the long game.’

The song did not go down well with fans – to put it lightly – and the duo were hit with major criticism in the comments of their video.

‘I don’t get why this is funny, I find it disrespectful,’ one person wrote, while another agreed it was ‘extremely disrespectful to Princess Diana’ and ‘not funny.’

‘This is incredibly distasteful,’ one person said. ‘The lengths you’re willing to go to or a viral moment,’ another mocked.

One even described the song and accompanying video as ‘evil’.

She is not the only public figure to attract backlash in recent days over comments about Diana and Camilla: Royal commentator Jennie Bond was accused of ‘tarnishing and exploiting’ the late Princess.

During an interview with Sky News, she claimed Diana had told her Camilla ‘had been loyal, discreet, and deserved some form of recognition.’

Bond added: ‘Well, she’s going to get it on Saturday.’

Diana and Charles split in 1992 and they divorced four years later, mere months before the Princess of Wales died from injuries sustained in a car crash in Paris.

Camilla and the future King married in 2005.

Vickers’ track was uploaded to Instagram the day before the coronation of King Charles, which is due to begin on Saturday at 11am.
