On Saturday, the famous royal siblings were spotted in west London as they attended a friend’s bachelor party.
The Telegraph reports that the stag — that’s what they call bachelor parties across the pond — belonged to close friend Thomas van Straubenzee.
Harry, 28, stayed comfy in a charcoal shirt, jeans and sneakers while his 30-year-old brother kept a low profile in a fleece, jeans and an orange cap.
The royal family will soon be gearing up for the arrival of Prince William and wife Kate Middleton’s first child. The Duchess of Cambridge is due in July.
