Meghan Markle and Prince Harry did invite Prince William and Kate Middleton to Lilibet's birthday party, a source says.
The Cambridges and their three children, George, eight, Charlotte, seven, and Louis, four, were reportedly invited to spend time with the Sussexes to celebrate their daughter's first birthday.
The Duke and Duchess of Sussex invited a number of close friends and family members to a low-key back garden picnic while attending the Queen's Platinum Jubilee celebrations.
