Eugenie shares a close bond with Harry and Meghan, and is currently residing at the Sussexes' Windsor home, Frogmore Cottage.
The Princess was reportedly one of the first members of the royal family to know about Harry's relationship with former actress Meghan when they first began dating in 2016.
Eugenie and Jack tied the knot at St George's Chapel in October 2018, just five months after Harry and Meghan were married at the same venue.

Harry and Meghan are now living in the US after stepping back from royal duties in March 2020, but they could be reunited with the royals if they return for a number of planned high-profile events this summer.
While the Queen will mark her 95th birthday at Trooping the Colour, the Duke of Edinburgh will also celebrate turning 100 in June.
Eugenie's son is the Queen's ninth great-grandchild after she welcomed Harry and Meghan's son, Archie, as her eighth in 2019.
