Some have argued that the reason behind the split comes down to the brothers differing roles in the Royal Family, but one royal expert has claimed that William and Harry didn't see each other for six months after the Royal Wedding, despite at the time, living in the same Kensington Palace area.
This week, however, the royal brothers stood side-by-side at a Polo Charity Match. All eyes were on new mum Meghan Markle and baby Archie, as well as Kate Middleton and her three children Prince George, Princess Charlotte and royal scene-stealer Prince Louis.
William's team came out victorious against Harry's in a narrow 7-6 win. Harry took the loss graciously, and he smiled at William, put his arm around him and kept it placed on his back as they posed for photos.
Many royal fans claim this is marking the official end of the 'royal feud' - especially considering Meghan and Kate's united display from the sidelines. The families appeared to be enjoying the day out, quashing the speculation that there is also tension between the Duchess of Sussex and the Duchess of Cambridge.
There you have it. We're putting this one to bed.
