LOOK: Queen Elizabeth officially signs off on the upcoming Royal wedding

Her Majesty Queen Elizabeth has formally endorsed the upcoming Royal wedding of Prince Harry and American actress Meghan Markle.

Below is the official tweet from the Royal family bearing the official approval of the Queen with a hand written signature at the top of the official document.

The document incorporates the symbols of America onto traditional vellum to represent the bride.

The Queen actually signed the Instrument of Consent in March, at the top of a vellum document transcribed in calligraphy and issued under the Great Seal of the Realm.

The document reads "Now know ye that we have consented and do by these presents signify our consent to the contracting of matrimony between our most dearly beloved grandson Prince Henry Charles Albert David of Wales KCVO and Rachel Meghan Markle."
