The once-in-a-lifetime celebration honors the queen’s historic 70 years on the British throne.
Prince Harry and his entire family will also be attending, a spokesperson announced (viaCNN).
One royal expert, however, says otherwise.

Will Archie and Lilibet be a delight or a burden for the Queen?
Queen Elizabeth is a doting great-grandmother in addition to being a monarch.
But royal biographer Angela Levin thinks the Sussexes should have picked a better time for a family reunion.

“The Queen is going to be very heavily in demand.”
Levin added that Harry and Meghan should have been more considerate.
Like other anti-Harry pundits, Levin thinks their Jubilee trip is just an attention-getting ploy.
“But with so much going on during the Jubilee, it is just the wrong time.”
