Next month the Royal family will meet the Trump family.

Many of the details during the three-day trip are still being finalized, but during this official state visit Trump will be feted by Queen Elizabeth II at a lavish banquet dinner on June 3, that his children are expected to attend as well, according to a White House official.

While no official schedule has been released, if the young Trumps -- Ivanka Trump and Jared Kushner, Tiffany Trump, Donald Trump Jr. and Eric Trump and his wife Lara -- do attend the official state banquet, they could meet the young royals -- Prince William and his wife Kate -- who are also expected to attend the event.

However, the White House and Buckingham Palace are still discussing a final schedule, and as a matter of protocol Buckingham Palace will not put out the guest list so far in advance.

Buckingham Palace would not comment for this story.

A White House spokesperson declined to comment on the news that Trump's children will be joining him on the trip.

The queen has hosted two previous state visits for U.S. presidents, President George W. Bush and first lady Laura Bush made a state visit in November 2003 and President Barack Obama and first lady Michelle Obama made a State Visit in May 2011.
