Prince William and Kate made no efforts to introduce their kids to Harry's family
Things are still icy between the royal brothers.
The Duke and Duchess of Cambridge reportedly made "no effort" to introduce their children to Prince Harry's family.
According to reports, the brothers failed to introduce their children to one another.
This was the first time all of their children were in the same country together.
However, Lilibet and Archie never met with William and Kate's three children.
A source close to the royals told US Weekly:
"William and Kate made no effort at all to introduce Prince George, Princess Charlotte and Prince Louis to Lilibet."
The brothers are still on bad terms after Prince Harry stepped down as a working royal.
During the Jubilee Weekend, they reportedly didn't even speak.
"As far as I know, nobody believes they spoke to each other."
Prince William is reportedly still angry at his brother for speaking about his private life on such a public scale.
"I think what it boils down to is not only what’s happened in the recent past.
"The Royal family is terrified about what’s going to be contained in the book Harry is going [to] be publishing at the end of this year."
It is believed Prince William, Kate, and their three children were invited to Lilibet's birthday party.
Prince Harry and Meghan invited the Cambridges to their daughter's party at Frogmore Cottage.
However, the family denied the invite due to prior engagements.
The Cambridges had royal engagements in Wales on the day of the party.
Prince George and Princess Charlotte even joined their parents for the visit.
Lilibet turned 1 on June 4th.
She may not have met her royal cousins, but she did meet her great-grandmother, Queen Elizabeth.
It is believed the monarch was eager to meet her namesake and cleared her schedule to do so.
