Prince William will be Prince Harry’s Best Man! Breaking Celebrity News has learned that the 33-year-old asked his big brother to stand by his side during his royal wedding to Meghan Markle.

As readers know, the event will take place this May 19 at Windsor Castle in England.

“Prince Harry has asked his brother The Duke of Cambridge to be his Best Man at his wedding to Ms. Meghan Markle,” wrote Kensington Palace in a statement this Thursday.

And if that wasn’t already a sign of brotherly love, William’s response was even sweeter.

“The Duke of Cambridge is honoured to have been asked, and is very much looking forward to supporting his brother at St George's Chapel, Windsor on May 19th,” tweeted the Palace along with a throwback photo of the two royal siblings.

The Palace also reminded fans that Harry served as Will’s best man when he married Kate Middleton in 2011. The couple had two kids soon after, and just welcomed their third child this Monday, April 23.
