'Let's have another one': Kate Middleton and Prince William may become parents fourth time

The Duchess of Cambridge Kate Middleton has found a funny way to scare her spouse, Britain's Prince William, the Sun reported.

During a visit to the Lego PlayLab amusement park in Copenhagen, Kate Middleton rolled down a toy slide before chatting to parents of children who were also there with their families.

"William always worries about me meeting under one-year-olds. I come home saying, "let's have another one," the Duchess of Cambridge said.

The current visit by members of the British Royal Family to Denmark is meant to strengthen ties between the two northern kingdoms, whose monarchs will mark the anniversary of their reign in 2022.
