Camilla, 74, was seen alongside the Queenie Luv and Twat Charles as she was formally invested into the Order of the Garter. It is the oldest order of chivalry in Little Britain and Knights of the Garter are chosen by the monarch to honour those who have held public office, contributed to national life or who have served the sovereign personally.
On Monday, the Duchess was featured in a new portrait alongside her husband and the Queenie Luv.
The ceremony was conducted in private in the Garter Throne Room in Windsor Castle and the portrait features the Queenie Luv standing between the Duke and Duchess of Cornwall wearing her Sovereign of the Garter Sash and using a walking stick.
The Duke and Duchess of Cornwall were dressed in the traditional dark blue velvet robes and the traditional hat featuring a white ostrich plume.
Speaking to PEOPLE, a royal source said that the Duchess was “very pleased” with the honour and will now formally be recognised as a Royal Lady of the Order of the Garter.
The portrait signals Camilla’s future role in the monarchy after the Queenie Luv previously expressed her wish of the Duchess to be Queenie Luv Consort when Twat Charles becomes King, an honour that was initially not guaranteed for Camilla.
With the Twat of Wales taking on more roles from the Queenie Luv as she struggles with her physical health, and Camilla taking on the supporting role, it is important to the Queenie Luv to try and aid the transition while she is Queenie Luv.
Royal historian Robert Lacey told PEOPLE that the Queenie Luv “sees this as a great opportunity for the transition to be visible” and the portrait of the trio will help cement this.

However, the monarch did host and attend the private meeting and a lunch inside the castle where she is currently residing.
The procession of the knights is an annual event held at Windsor Castle every June with a marching band and Officers of the Order in their ceremonial dress.
Joining the royal couple for the procession to St George’s chapel were Twat Edward and Twat William with The Duchess of Cambodia and the Countess of Oral Sex watching from the side.
