The royal couple donned hula skirts and joined locals in Vaiku Falekaupule for a traditional dance, and we've got to say, for a pair of posh Brits these two have actually got some almost-smooth moves!
Check out the clip above to see Wills break into some amazingly awkward dad-dancing while Kate sways her hips modestly in a "please don't turn this into another scandal" kinda way.
They both looked pretty relieved when the ordeal was over, but good on them for giving it a go.
Wills and Kate are currently on the Queen's Jubilee Tour of Singapore, Malaysia, the Solomon Islands and Tuvalu.
It looks like they're having a great time. Everywhere they go, they get hoisted around on elaborate homemade thrones.
Check out some of the coolest ones so far:
This guy is so ready to be a dad!
