The two lovebirds are sharing sweet tweets once again, publicly showing their love for each other is as strong as ever.
Former cricketer Shane, who flew to the British capital to be with Elizabeth as she began filming E! series The Royals, wrote on Wednesday: "Had fun on set yesterday with you angel, good luck today & hope my exquisite line reading last night works well too!"
Shane, 44, completed the personal message with a good luck kiss.
The pair were spotted wrapped up warm against the cold chill in London, where Elizabeth is currently filming as the Queen.
On Thursday, the model and actress took to Twitter to share an on-set snap of herself. "God Save the Queen. Me as HRH Queen Helena today. Still shivering. Nurofen Cold and Flu please," she wrote.
In the picture, Elizabeth, 48, looks glamorous in an all-black ensemble complete with black heels, a vintage-style handbag, and an elaborate fascinator as she filmed in London's iconic Trafalgar Square.
The brunette's tresses were perfectly coiffed for the scene, which appears to be a funeral. A sombre-looking Elizabeth can be seen mourning alongside a man in uniform with a number of other guests and a few of the Queen's guards nearby.
A coffin – which was strewn with a patriotic flag – lies ahead, and may contain a fictional member of the fictional blue-blooded family.
Elizabeth's filming of the drama comes days after she laid rumours to rest that she is trying for a baby.
The brunette, who has recently gone through a "rocky patch" with her boyfriend Shane, set the record straight on Twitter, telling her followers: "PS contrary to ludicrous reports, family, friends & followers, I am certainly not trying to have a baby.....mind boggling."
