Middleton, accompanied by husband Prince William, visited a farm in Cumbria, England, on Tuesday. During their visit, the royal couple met with a family with two young girls.
At one point, in a video of the exchange shared by The Royal Family Channel, someone mentions one of the girls — ages 3 and 5 — thought Middleton would arrive at the farm wearing Elsa’s iconic blue, shimmery dress.
“I know, I’m sorry. I came in my trousers and my coat because I’m going to see some sheep,” Middleton says in response.
Later, both Middleton and the Duke of Cambridge sheared sheep.
The sweet exchange comes after Prince William appeared to call his daughter Princess Charlotte by an adoring nickname.
