He has already beaten king of sprint Usain Bolt in a race – and now Prince Harry has made light work of US Olympic swimmer Ryan Lochte.
The unlikely pair went stroke for stroke after meeting at a Las Vegas pool party, and despite his eleven medals, Ryan was left floundering.
But just as the third-in-line 'cheated' his way to glory against Usain during his Caribbean tour, Harry again resorted to underhand tactics to beat his latest opponent.
The royal only won the 3am pool race after a fellow holidaymaker kept Ryan at bay by clinging onto his legs.
The New York Daily News' website posted online footage of the fun-filled encounter which also showed Ryan getting his revenge by beating the Prince in a breaststroke race. On that occasion there were no aides around to assist Harry's shot at glory.
Both are enjoying a holiday in Sin City after their respective roles at London 2012.
Prince Harry took on the mantle of Olympic ambassador with his brother Prince William and sister-in-law the Duchess of Cambridge.
And five-time gold medalist Ryan was powering through contests at the Aquatics Centre – most notably beating Michael Phelps to take top podium spot in the 400m individual medley.
Harry's high jinks in Las Vegas have generated headlines around the globe, with compromising pictures of the Prince surfacing on the internet.
The photos, in which he appears to be naked reportedly playing "strip billiards" with a group of friends, are thought to have been taken last Friday.
St James's Palace has confirmed that it is the Prince in the photos but is making no further comment about the images.
