Prince Harry looks like a portrait of King Philip IV of Spain, according to a hilarious app

A new app that finds dopplegangers reveals that Royal Family look like their ancestors - including Harry baring a striking resemblance to a Spanish King.

And even his big brother Prince William got in on the act - closely resembling a 400-year-old painting of Prince Philip William of Orange by Michiel Jansz van Mierevelt (corr).

The new Google Arts and Culture app, which matches selfies to fine art, has taken the internet by storm - with celebrity users including Kate Hudson, Sarah Silverman and Zach Braff.
