On April 26, Kensington Palace confirmed that Prince Harry has indeed asked Prince William to be his best man. William is "honored to have been asked" to support his brother on his wedding day.
Back in December, Prince Harry attended the London Fire Brigade Carol Service at Westminster Cathedral amid reports that he had asked his brother to be his best man at his upcoming wedding to Meghan Markle. "Harry has several close guy friends, but there's no way he would ask anyone but William to take on the top job," Us Weekly reported at the time. Harry also served as William's best man at his 2011 wedding to Kate Middleton.
