An awkward encounter occurred between Denzel Washington, star of 'Gladiator II', and King Charles.

During the "Gladiator II" premiere, King Charles III shared a memorable moment with Hollywood actor Denzel Washington.

King Charles, who was present at the premiere without Queen Camilla due to her ongoing chest infection, greeted the cast of "Gladiator II" at the ODEON Luxe Leicester Square in London.

King Charles met with cast members, including Washington, Pedro Pascal, and Paul Mescal, as well as director Sir Ridley Scott during the meet and greet. Despite this, Washington seemed anxious when he encountered the royal monarch.

Washington smiled as he gave Charles a handshake, unsure if he was supposed to grab his hand or not.

"I’m just an awful man, you’ll see," Washington said, as he stumbled on his words. "I’m a lovely chap."

Washington, who has been in numerous films, was praised by King Charles as being fantastic.

Queen Camilla had to cancel events last week due to a chest infection.

Her Majesty was advised to take a "brief respite," effectively canceling Camilla's upcoming events until further notice.

The BBC reported that a statement from the palace read that Her Majesty The Queen is currently unwell with a chest infection and has been advised by her doctors to take a short period of rest.

"Her Majesty regretfully withdrew from her engagements for this week, but she hopes to recover in time to attend the Remembrance events as usual."

Last weekend's events were not attended by her, as she was unable to make it.

After Buckingham Palace announced King Charles III's cancer diagnosis in February, Queen Camilla developed a chest infection.

"A form of cancer was discovered during the King's recent hospital procedure for benign prostate enlargement, according to Buckingham Palace."

In April, His Majesty resumed his public responsibilities after a brief rest.

The palace later announced that the Princess of Wales was also fighting cancer.

Kate Middleton underwent planned abdominal surgery and was told her condition was non-cancerous. However, further testing revealed cancer was present. Her medical team advised chemotherapy.

The Princess of Wales stated in a pre-recorded message in March that the news came as a huge shock and she and William have been working hard to process and manage it privately for the sake of their family.

"It has taken time for me to recover from major surgery and for us to explain everything to George, Charlotte, and Louis in a way that is appropriate for them, and to reassure them that I am going to be okay."

Their Royal Highnesses, Prince William and Princess Kate, are the proud parents of three adorable children: Prince George, Princess Charlotte, and Prince Louis.
