The Duchess of Sussex was left in stitches as she and Prince Harry were serenaded with a song about mosquitoes during a visit to the oldest school in the Pacific.
The Tupou College boys' choir sang a tune complete with flying actions and buzzing noises to welcome the couple to its on-site forest.
Meghan was delighted by the comedic song, and was pictured wiping tears from her eyes as she laughed hysterically during the performance.
The Sussexes were there to dedicate two of the school's rainforest tracts to the Queen's Commonwealth Canopy.
The aim of the song was to frighten off any mosquitoes that may have been flying around.
Meghan, wearing a blue Veronica Beard dress, looked radiant as she giggled at the song.
She gave the boys a huge round of applause at the end of their performance.

The original plan was for the duke and duchess to walk through the Tuloa forest together, but in the end only Harry did.
The duke and duchess have now flown back to Sydney for the Australian Geographic Society Awards at the Shangri-La Hotel on Friday evening.
