WATCH | Frans Steyn challenges Prince Harry to a 'down down'!

Cape Town - It was all fun and games in the Springboks' changing room following their 2019 Rugby World Cup victory over England on Saturday.

Beer flowed, Siya Kolisi threw shapes, Faf de Klerk waltzed around in his underwear ... and Frans Steyn challenged Prince Harry to a 'down down'.

Prince Harry’s England team may have lost 32-12 to the Springboks, but that didn’t stop the prince from joining the celebrating South Africans.

After "Beast" Mtawarira asked Prince Harry to say a few words, Steyn, who became just the second Springbok after Os du Randt - and 21st overall - to win multiple World Cups - interjects, offering their royal visitor a beer.

For a moment it appears the once rebellious prince considers the challenge, but then declines and points to the cameras, suggesting he would've been game had there not been a risk of his actions being beamed around the world - and appearing on websites...

It's clear marriage and fatherhood has matured the now 35-year-old Prince Harry.
