The 56-year-old flaunted her age-defying looks to over 2.3 million followers in a series of snaps featuring her in a blinding tiara behind the scenes of the show.
“The Royals has dropped on @netflix All 4 seasons,” she wrote in celebration.
“Such glad memories of creating such a fun, silly show a few fictitious British Royal Family!”
The actress treated her followers to footage of herself on-set in nothing greater than smoky eyeliner and a sheer white lace embroidered dress.
While camera equipment might be seen within the background, Liz posed for her own more personal and intimate pictures behind the scenes.
Other snaps include a pouting Liz beside Joan Collins, while wearing a glittering silver dress.
Despite looking sensational within the lace dress – and, in one other snap, a black thong lingerie set – Liz has previously admitted she has little interest in extreme diets.
Other photos she uploaded to her post included certainly one of herself on-set along with her 19-year-old son Damian, who had a cameo role within the show.
Meanwhile in one other, she donned a waist-hugging strapless black dress, paired with sexy fishnet tights, proving that the fictional Queen Helena is sizzling when not on the throne.
The snaps give a preview of what type of visuals fans can expect after they tune into the Netflix show.
“Gorgeous minx!” @gigilevangie exclaimed, while @ann_caruso begged: “More seasons, please!”
