“Don’t expect anything wild,” a source tells Us of Harry’s upcoming celebration.
As previously reported, Harry, 33, asked his brother, 35, to be his best man for his wedding to Meghan Markle, which royal palace officials confirmed will take place at Windsor Castle’s St. George’s Chapel in May 2018.
“Harry has several close guy friends, but there’s no way he would ask anyone but William to take on the top job,” the source told Us.
A palace aide insists the big day —set to be televised — will have a boisterous side, and Harry and Markle “are totally in charge” of plans for both the ceremony and reception.
“It will be fun and joyful,” the aide adds.
“Harry asked the queen for permission last month,” the source explained to Us. “And she is delighted to have Harry bring his fiancée. It is a family occasion, after all, and Meghan is very much family now.”
The royal Christmas plans include exchanging gifts and having dinner together on Christmas Eve. The following day, the group heads to an 11 a.m. Christmas Day service and later indulges in a three-course dinner and chocolate yule log.
“They’ll be William and Kate’s guests and travel back and forth with them,” the source told Us.
