Meghan Markle had a serious case of the giggles during a choir performance in Tonga today. The Duchess just couldn't control her tearful laughter while watching the Tupou College Boys Choir sing a mosquito song during a ceremony on the island of Tongatapu.

The choir was singing mosquito-themed song about warding off the pesky bugs. The boys completed the performance with buzzing noises and bug-like choreography.

The mom-to-be laughed and wiped away tears, often turning to husband Prince Harry to giggle at the song.

The Duke and Duchess of Sussex were on Tongatapu to dedicate two of Tonga's rainforests to the Queen's Commonwealth Canopy—the Toloa Forest Reserve and the Eua National Park Forest Reserve, which is on another island.

"My wife and I are so pleased to be here today to mark the dedication of not one, but two forest areas to to the Queen's Commonwealth Canopy Initiative, which started in 2015 in honor of my grandmother's lifetime of service to the Commonwealth," Prince Harry said in a speech.

"The Toloa Reserve, the last remaining forest area on mainland Tonga, is home to several dozen species of plants and trees that have many uses: producing fruit (including durian and plums), timber, medicine, oils and much more. It’s also incredibly beautiful!" Scobie wrote on Twitter.
