The royal family are planning a show of support for Kate Middleton at an event that falls on the same day the final episodes of Harry and Meghan's Netflix show are released.
Prince Harry and Meghan Markle have sent shockwaves across the world as their upcoming Netflix documentary is more or less all anyone can talk about.
The first instalment of their docuseries will come out on Thursday, but the final instalment will be released the following week - on the same day as Kate's concert, reports the Mirror.
Two previews have sent the internet into a frenzy in the last week and, in the latest teaser, the couple discuss royal family hierarchy.
In one bombshell claim, Prince Harry says stories are 'planted' in the press.
Harry says in the second trailer: "There's a hierarchy of the family. You know, there's leaking but there's also planting of stories. It's a dirty game."
Meanwhile, it was confirmed weeks ago that the Princess of Wales would be holding a second annual service at Westminster Abbey next week that will feature a tribute to the late Queen.
As the final episodes of the Netflix docuseries drop, the royal family will rally around Kate at the event as King Charles, Queen Consort Camilla and Prince William will be in attendance.
It's thought the carol service will be dedicated to the late Queen "the values Her Majesty demonstrated throughout her life, including duty, empathy, faith, service, kindness, compassion and support for others".
Spearheaded by the Princess of Wales and supported by The Royal Foundation, the service will "recognise the selfless efforts of individuals, families and communities across the UK, and celebrate and showcase the joy that human connection and togetherness can bring".
There will be performances from Craig David, Alexis Ffrench and Samantha Barks, as well as a special duet from Alfie Boe and former Spice Girl Melanie C.
The Palace have said "poignant readings" will be delivered by speakers including the Prince of Wales, Dame Kristin Scott Thomas, Hugh Bonneville and Kadeena Cox.
The service will be broadcast on ITV1 on Christmas Eve as part of a Royal Carols: Together At Christmas programme, narrated by Catherine Zeta-Jones, and featuring an introduction by Kate and tributes to Queen Elizabeth II.
The first three episodes of Harry and Meghan's series will be available on Netflix on Thursday (December 8).
