At least outwardly everything looks harmonious: despite all the tensions, the British royals congratulated Duchess Meghan on their official social media channels on their birthday.

For the photo of a radiant Meghan, who celebrates her 41st birthday on Thursday, both Prince Charles and Duchess Camilla as well as Prince William and Duchess Kate published their birthday wishes on Twitter and Instagram. This is particularly notable for the latter, as the relationship between the two couples, formerly dubbed the “Fab Four,” is said to be strained.

After enormous upheavals last year, when Prince Harry (37) and Meghan accused the royal family of lack of support and racism in a television interview, the waves have recently calmed down. Queen Elizabeth II (96) met the great-granddaughter Lilibet (1) named after her – Harry and Meghan’s daughter – and received the family, who now live in California, as part of her throne anniversary. However, with the forthcoming publication of Harry’s memoir, new tensions threaten.
