An Australian news reader was extremely apologetic after being overcome with laughter while reporting on some seriously unfunny news during a recent broadcast.

Natasha Exelby, Channel Ten's Late News presenter, was still giggling after some banter with colleague Matt Doran, and couldn't seem to shake it off before reading a report on the latest rioting in Brazil and a collapsed building in Mumbai that claimed the lives of five children.

She concluded her report by apologizing to anyone she offended with her extremely unfortunate "case of the giggle."
