The Duke and Duchess of Cambridge rule when it comes to sharing spectacular moments together.
And the couple couldn't be happier that Prince Harry now has that with Meghan Markle.
As Prince Harry prepares to wed Meghan Markle at the royal wedding, we look back at the other leading lady in his life - Duchess Catherine! These two have such an unbreakable bond.
Kate's heartwarming dynamic with her "little brother" always has royal watchers smiling from ear to ear.
Whether they're at official functions together, cracking up on the balcony of Buckingham Palace, or flashing their signature grins for the cameras – you can always count on Kate and Harry to significantly brighten your day.
In the rare moments that Captain Wales talks about his family, he has nothing but loving words for Kate.
"To have a big sister is very, very nice...She's a fantastic girl, she really is, my brother is very lucky," Harry says.
"Prince Harry adores his brother and says Catherine is the sister he never had," a royal source adds.
Before Catherine watches her little brother make a lifetime commitment to Meghan Markle, we look back at Kate and Harry's special bond.
