Prominent members from Europe's royal families have gathered in Greece for the funeral of the late King Constantine II.
His family hosted a dinner at the Hotel Grande Bretagne in Athens on the eve of the service, with guests including the Spanish royals, King Carl Gustaf and Queen Silvia of Sweden, and Crown Prince Haakon and Crown Princess Mette-Marit.

And as the party left the hotel at the end of the dinner, there was a very unexpected moment that had royal watchers doing a double take.
Queen Letizia was photographed linking arms with Marie-Chantal and gently touching her hand. Both women could be seen smiling as they followed behind the princess' husband, Pavlos of Greece – Constantine's eldest son.

The tender moment between the two ladies came as a surprise to fans. it was thought they were on bad terms following an incident involving Letizia's mother-in-law, Queen Sofia of Spain.

Footage of the moment was quickly shared online – and Marie-Chantal didn't hold back when it came to voicing her opinion on the tense scene.
"This makes me feel so angry," she commented, before telling another Twitter user: "No grandmother deserves that type of treatment! Wow she's shown her true colours."

Crown Prince Pavlos is a nephew of Queen Sofia, which is perhaps what elicited the strong response from Princess Marie-Chantal.
It's the second time in a matter of months that the two ladies have reunited. Both were in attendance at the funeral for Queen Elizabeth II in September last year, although it is not thought they shared any exchanges.
