The King has been supporting Lady Gabriella Kingston since the unexpected death of her husband, Thomas Kingston, in February.
And now it's been reported that he and the Queen have invited Ella, as she is known to friends, to attend the King's Birthday Parade on 15 June – formally known as Trooping the Colour.
A royal source is said to have told The Daily Mail's Richard Eden that everyone is hopeful that Lady Gabriella will attend the celebrations "if she feels up to it".
It comes ahead of a very difficult anniversary for Ella, who is the daughter of the late Queen's cousin, Prince Michael of Kent and his wife, Princess Michael of Kent.
Saturday 18 May would have marked her fifth wedding anniversary with Thomas, who was found dead at the age of 45 at his parents' home in the Cotswolds on 25 February. An inquest at Gloucestershire Coroner's Court on 1 March found that the financier died from a "catastrophic head injury" and a gun was found near his body. His death was not treated as suspicious, and no one else was involved.
The Prince of Wales was among the royals to pay their respects at Thomas's funeral at the Chapel Royal at St James's Palace in London on 12 March.
If Lady Gabriella were to attend Trooping the Colour, it would mark her first public appearance since her husband's death. The couple were last pictured together on Valentine's Day as they attended a Shakespeare event with Queen Camilla in London.

Lady Gabriella and Thomas, who were introduced by mutual friends, first began dating in 2015. Three years later the financier proposed to Ella on the Isle of Sark in 2018.

In particular, Their Majesties send their most heartfelt thoughts and prayers to Gabriella and to all the Kingston family."
