Queen Letizia and King Felipe of Spain hosted a diplomatic meeting during the week, but one moment stunned royal watchers.
The royal couple greeted ambassadors individually by shaking their hands, but when it came to the Iranian ambassador, Hassan Ghashghavi, he only offered the courtesy to Felipe. In the video below, you can see how Letizia reacted to what some have been dubbing as a "snub".

The Spanish royal looked incredibly glamorous for the event, as she wore a a sweet pussybow blouse in a sumptuous silk fabric. She channelled movie magic with her skirt selection, a flowing blossom pink skirt.
What did you make to the moment?
Despite the moment, Letizia is unlikely to be holding a grudge with the Iranian ambassador and earlier this month she put a long-standing feud behind her.
Following the funeral of King Constantine, she was photographed linking arms with Princess 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.
Their disagreement stemmed from a controversial clash between Letizia and Queen Sofia, her mother-in-law, at the Cathedral of Palma de Mallorca after the 2018 Easter Mass.

Letizia was filmed seemingly blocking photographers from taking photos of Sofia with her granddaughters by standing in front of the trio, and then removing Queen Sofia's hand from Infanta Sofia's shoulder.
