A viral TikTok clip shows a sweet post-wedding conversation between Kate and William.

The clip involves William telling Kate "you look happy" and her responding "yes!" before asking "are you happy?"

William and Kate tend to be private about their relationship, but have discussed it in the past.

In a post-engagement interview, William said he knew there was something special about Kate when they first met.

They became friends first, which they believe is an advantage in their relationship.

Kate said she felt shy and went bright red when she first met William.

The couple got married on April 29, 2011 in an extravagant ceremony.

They will celebrate their 12th wedding anniversary soon.

The sweet post-wedding conversation shows the love and affection between the royal couple.
