Pharrell, 40, took to the stage at The Future Music Festival in Australia yesterday (10 March) and stripped down to just his camouflage shorts.
With temperatures in Adelaide topping 30C, we guess the US rapper was feeling a little hot and sweaty as he rocked out to the screaming crowd.
Pharrell was, of course, wearing his trademark Vivienne Westwood grey hat and a pair of trainers and performed hits including Daft Punk's 'Get Lucky' and 'Blurred Lines'.
A Pharrell gig wouldn't be complete with his smash hit single 'Happy' either!
During his stint onstage, Pharrell even invited 20 lucky girls up to sing along with him - and one got to wear the hat. Jealous? Us too!
Pharrell jetted in to Australia last week and has been busy performing in Melbourne, Sydney and taking part in lots of TV and radio interviews.
Later this week, he is due to fly to Malaysia to perform at The Future Music Festival's Asian leg.
