Following the release of a sweet video clip of the Duke and Duchess of Cambridge's children playing in Kate's specially designed plot for the Chelsea Flower Show, eagle-eyed fans noticed Prince William calling his daughter by an unusual name; 'Mignonette'.
Although most of the clip is subtitled, there is a brief section where William is speaking to his only daughter playing on a rope swing which isn't closed captioned.
WATCH! The video that has people believing Prince William has coined Charlotte a French nickname!
Observant royal watchers were quick to take social media and claim William was calling his daughter by a sweet nickname, 'Mignonette'.
The Duke and Duchess of Cambridge are very pleased to share some new photographs of their family as they visited the RHS Back to Nature Garden at the #ChelseaFlowerShow on Sunday afternoon. The photographs were taken by @mattporteous. The #RHSChelsea Back to Nature Garden, designed by The Duchess and award-winning landscape architects Andrée Davies and Adam White of Davies White Landscape Architects, is a woodland setting for families and communities to come together and connect with nature. Her Royal Highness is a strong advocate for the proven benefits the outdoors has on physical and mental health, and the positive impact that nature and the environment can have on childhood development in particular. Over the past months, Prince George, Princess Charlotte and Prince Louis have helped The Duchess gather moss, leaves and twigs to help decorate @The_RHS Back to Nature Garden. Hazel sticks collected by the family were also used to make the garden's den. The Duchess told Monty Don in an interview for the BBC: "I really feel that nature and being interactive outdoors has huge benefits on our physical and mental wellbeing, particularly for young children. I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together."
Mignonette is diminutive from the French word 'mignon', meaning 'cute'.
One Twitter user wrote: "Anyone notice right before he asked Charlotte to push him, he called her by a lovely nickname. Someone from KP IG's (Kensington Palace Instagram's) comment section suggested William called her "Mignonette" which means "delicate"."
While another royal fan tweeted: "Mignonette I think - cutie. Not 100 per cent though."
