Holly Willoughby became very emotional as Monday's This Morning began and a brand new filming location was revealed.
As the latest episode of the ITV daytime show began, Gyles Brandreth entered the studio accompanied by two 'royal guards' who were playing trumpets.
Reading from a piece of paper, Gyles said: "Dear Mr Schofield and Ms Willoughby, you have been given a royal appointment for tomorrow as we will be broadcasting live from Buckingham Palace to mark Her Majesty's platinum Jubilee.
"You will be taking a look back at the Queen's magnificent 70 years of Sovereign with a host of special guests," he continued.
"We look forward to welcoming you live from 10 o'clock tomorrow morning as the celebrations begin at Buckingham Palace."
Squealing with delight, mother-of-three Holly said: "That is so exciting! that's gonna make me cry!"
"Beautifully done, any tips?" Phillip said, before asking Gyles: "Will you be there as well?"
"No tips but oh yeah, I'll be in the Oak Room looking after you, don't worry," Gyles joked.
"How exciting, Downton Abbey and now Buckingham Palace, we do get the keys to all the best houses in Britain don't we?" Holly said to Phil.
"We really do," Phillip replied before saying: "But this is the best one!" as Holly agreed and added: "I think it is! Doesn't get better!"
This Morning airs weekdays at 10am on ITV and ITV Hub.
