Prince Harry and his wife Meghan Markle, who are expecting their first baby, are currently on a 16-day tour of Australia, New Zealand, Fiji and Tonga.

During a trip to the island of Tonga, which has seen an outbreak of the mosquito-borne Zika virus over past few years, the pregnant Duchess of Sussex, Meghan Markle, accompanied by her beloved husband, Prince Harry, were serenaded with an apt song.

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.
