On Tuesday, the Queen reassured she was 'on the mend' as she conducted her first public engagement after contracting a 'nasty' chest infection.
It comes after King Charles made a film-star worthy entrance as he arrived for the Gladiator II world premiere at Leicester Square last night in his state Bentley limousine.
The royal watched the highly anticipated blockbuster, hot off the heels of a glittering reception he and Camilla hosted to celebrate the centenary of the Film and TV Charity.
He looked dapper in a black tuxedo, teamed with a bowtie, at the red carpet where the monarch smiled for the cameras.
Earlier in the evening, Charles and his wife chatted with A-listers including the film's director Ridley Scott as they welcomed a slew of stars to Buckingham Palace.
While acting legend Denzel Washington, who had been expected to attend, was a no-show, is expected to meet the King tonight at the premiere.
Charles will also meet the movie's stars including Paul Mescal, Connie Nielsen and Pedro Pascal - before settling down to watch a screening.

Queen Camilla, who has had to pull out of the event due to an ongoing chest infection, earlier told Ridley: 'I am so sorry I'm not coming tonight. I'd be coughing throughout it. '
Indeed, the Queen discreetly coughed several times during her shortened appearance at the reception and gratefully sipped on a glass of water, saying she had felt 'absolutely rotten' last week but was definitely 'on the mend'.
The King met the stars of Gladiator II and asked Hollywood legend Denzel Washington : 'Are you playing someone terrible?'
