Prince William and Kate Middleton are giving the cold shoulder to their niece, Lilibet.

Lilibet is Prince Harry’s youngest child and only daughter. He and Meghan Markle also have Archie (3).

As you may already know, the relationship between Prince William and Prince Harry is very strained.

Harry’s marriage to Meghan Markle ruffled too many royal feathers, and their subsequent move to California after leaving their royal duties didn’t help the relationship either.

In recent years, Harry has gotten back into the good graces of Queen Elizabeth II and his father, Prince Charles.

The family of four is set to fly over to England to celebrate Lilibet’s first birthday this coming weekend.

It just so happens that Kate and William will be over 100 miles away from the party.

They’ll be tending to royal duties in connection with the Platinum Jubilee celebrations.

According to the Daily Mail, William and Kate will meet with performers and crew involved in the special Platinum Jubilee Celebrations Concert taking place on the grounds of Cardiff castle.
