A viral video of a nude man escaping from a window at Buckingham Palace has been exposed as a stunt for Elizabeth Hurley's new U.S. Tv series The Royals.

Footage of the naked man climbing out of a window using bedsheets and ultimately falling on the grounds at the royal residence surfaced on YouTube last Friday (26Feb15), and it has since garnered more than one million views.

But it has now been revealed that the video was actually a hoax, and part of a campaign to promote the new series, which centres around the lives of a modern-day fictional British royal family, with Hurley as the Queen.

The Royals premieres in the U.S. on 15 March (15).
