Middleton, 38, and Harry, 34, represented the royal family at an Anzac Day service in London to honor Australian and New Zealand servicemen and women, especially their work in World War I. The pair were spotted laughing it up outside of Westminster Abbey for a church service.
William and Harry have reportedly been at odds since William questioned the speed at which Harry and Markle moved in their relationship.
“I’m told from very reliable sources that the relationship has gone through challenging times since Harry started dating Meghan,” royal expert Katie Nicholl recently told Fox News. “I’m told that privately William was concerned about how quickly the relationship had moved.”
“William wanted to make sure that Harry was making the right decision,” continued Nicholl. “And I think what was intended as well-meaning, brotherly concern and a bit of advice went down quite badly with Harry, who felt that William wasn’t being as supportive as he might’ve been. So there has certainly been tensions between the brothers.”
Meanwhile, reports have suggested that William urged Harry and Markle to work in Africa to be "as far away as possible" from Kensington Palace.
The palace said in a statement that no plans to move have yet been confirmed, but sources said that Harry indeed wants to separate himself from his brother and become his own man.
