Prince William and Kate Middleton don't show PDA often [1], but when they do, it's superadorable. Aside from cozying up during sporting events [2], there is one thing that Will does when they're not facing the cameras that is especially sweet — he touches Kate's back. Whether he's helping his wife down the steps, or he's pulling her in for a hug, we can't get enough of the pair's "touching" moments. And he's not the only royal with a signature move. Kate has her own way of showing off her love for Will [3]. See their discrete PDA below.
