Brothers William, 36, and Harry, 34, set up the Royal Foundation in 2009 to house all of their charitable ventures. Well, sort of. The "Fab Four" are predicted to officially split in June when Harry and Meghan announce that they are leaving The Royal Foundation, their joint charity.
It was only past year the Duke and Duchess of Sussex and Kate Middleton and Prince William came together for the charity's first Q&A forum.
Royal aides have, however, confirmed that the family will still collaborate on some projects together.
The president and his family may have hoped to meet the royal family's two shining stars-Duchess Meghan and her baby Archie Harrison.
A charity source told The Sun: "At the start of past year, the plan was that all four would work together and I really believed in them as the power of four".

Premier League heavyweights Arsenal and Manchester City have also been credited with an interest in the player. I think it probably helps Spurs more than us, I would say.
It's the latest development in the formal divide of the two royal households, following Harry and Meghan's move to Frogmore Cottage in Windsor.
They also now have separate social media accounts with the Cambridges using the KensingtonRoyal handle on Twitter and Instagram while Harry and Meghan created their own, very popular, Instagram account under the handle SussexRoyal.
"Certainly the animosity over status, money and Meghan meant that the split in their joint households had to be brought forward much more quickly than anticipated, so perhaps it was inevitable that their joint charity has to be slit too".
The news comes among feud rumours. William is future king and so is sometimes restricted in what he can do.
"The Sussexes want the flexibility of more commercial decisions".
According to The Sun, Buckingham Palace and Kensington Palace have declined to comment on the split.
