Ever since Prince Harry stepped back from royal life, there's been an evident coolness between the Duke and his older brother Prince William's relationship. The rift between the siblings and Harry's tension with his father Prince Charles has been widely reported on, but Harry has said how he's hoping to "heal" his relationship with his dad, and how he'll always love his big brother.
"I love William to bits, he's my brother, we've been through hell together, we have a shared experience, but we were on different paths," Harry told Oprah Winfrey in his interview in March.
The royals are indeed on different paths – living across the world from each other with William destined to be King one day, while Harry embraces his new freedom in the US.
But the first steps of reconciliation were seen during Prince Philip's funeral in April, when the brothers were spotted chatting together in a scene that looked like old times.
The pair were also reunited in July as they unveiled a statue of their late mother, Princess Diana, in the gardens at Kensington Palace.
As they sort through their matters privately, we're taking a look back to happier times when William and Harry showed their unbreakable bond.

Diana strived to give her boys as normal an upbringing as possible, which would mean taking them to theme parks and playgrounds like other kids.
"Behind closed doors, she was a very loving, caring mother and an incredibly funny person," Harry said on ITV documentary, Diana, Our Mother: Her Life and Legacy. "I think she lived a lot of her life, especially in private, through us and I think that childish fun element really came out when she was spending time with us."
He added: "She was our mum. She still is our mum. And of course, as a son I would say this, she was the best mum in the world. She smothered us with love, that's for sure."
