WATCH | A 'mosquito-repelling' song had Prince Harry and Meghan laughing in Tonga.

Pregnant Meghan Markle in tears of laughter as children sing her a song about mosquitoes

The Duchess of Sussex was left in stitches as she and her husband were serenaded with a song about mosquitoes as they continued their official royal engagements in Tonga.

The Tupou College Boys' choir sung a comedy riff complete with flying actions and buzzing noises to welcome the couple to the forest surrounding the school on Friday.

Prince Harry and his pregnant wife Meghan Markle were there to dedicate two of the school's rainforest tracts to the Queen's Commonwealth Canopy project, which conserves indigenous forests for future generations.

But the focus was more on the mosquitoes. The aim of the song was to frighten off any mosquitoes that might be buzzing around.
