Prince Harry made a valiant effort to reconnect with his estranged brother William and his family.

Over the weekend, Harry, Meghan Markle and some of the royal family celebrated the first birthday of their daughter, Lilibet.

The youngest child of the Duke & Duchess of Sussex had a big birthday on Saturday, June 4.

Meghan and Harry flew in from California late last week for Queen Elizabeth II’s Platinum Jubilee celebration.

William and Kate knew well ahead of time that the former royal members were going to be in the UK for the celebrations.

They decided to be out of town on the day of Lilibet’s birthday.

Page Six exclusively reports Harry & Meghan invited William and Kate over to UK home, Frogmore Cottage, on Saturday, to no avail.

The outlet reports there was no solo time spent between the Sussexes and Cambridges.

“Things are still fraught. William is still wary of spending any time alone with Harry as you never quite know what may be reported back afterwards,” an insider reports.
