Kate Middleton reveals Princess Charlotte's adorable nickname

AOL.com Editors

The older royals may mean all business, but we absolutely live for little snippets on the youngest generation of Windsors. Yes, we even kvell over their nicknames.

Kate Middleton was on royal duty last week during a surprise two-visit to Northern Ireland with Prince William. The duchess, who the night before showed off her bartending skills at a pub party, was chatting to royal well wishers during a walkabout. The mom-of-three asked one visitor about her children, who explained she had a 4-year-old son. 

The duchess then remarked he was about the same age as "Lottie," referring to Princess Charlotte.

We learned a few more things about our favorite family on this 48 hour tour, including how Prince George thinks his mom is "rubbish" at soccer, the Cambridges love the movie "How to Train Your Dragon" and Kate is feeling a little "broody" about baby number four. 

It's quite clear that Kate and William are like any other parents and love to gush about their kids. For more on their surprise tour, watch the video above.
