The Tupou College boys' choir sang a special song with an eye to scare off mosquitoes, and the tune was completed with flying actions and buzzing noises to welcome the royal couple.

Glowing in a sky blue dress, Meghan was apparently impressed by the performance and couldn't contain her emotions as she laughed her head off when listening to the song.

Her reaction sent social media into meltdown, with many saying that Prince Harry was a lucky guy, and were glad to see him happy with Meghan:

Others couldn't help but agree that the performance was indeed funny:

The royal couple visited the island of Tonga to dedicate two of the school's rainforest tracts to the Queen's Commonwealth Canopy. The initial plan was for Harry and Meghan to walk through the Tuloa forest together, but eventually the Duke did it alone.

Commonly, the Foreign and Commonwealth Office advises pregnant women to consider delaying non-essential travel to such countries, where they risk contracting the Zika virus.
