The sassiest child in showbiz turned three this week – and North West is as adorable as ever in the video mum Kim Kardashian posted to celebrate. Wearing a cute mermaid swimsuit, little Nori grins at the camera as Kim, 35, tries to make her promise to 'stay little forever'.
Alongside the clip Kim wrote: "She promised me she wouldn't get any bigger. I can't believe my baby girl is 3 years old today!!! Northie I love you so much I can't even explain it! Happy birthday to my favourite mermaid!"

Proud grandmother Kris Jenner reposted Kim's short clip and added her own sweet comment. She said: "Happy 3rd birthday to my little angel, my precious granddaughter North! I can't believe you're 3 today! You are growing into the most beautiful little girl!!! You bring us so much joy and I thank God every day for blessing us with you. I love you beyond words!"
Kim, who also shares six-month-old son Saint with husband Kanye West, shared another snap of Nori earlier this week, showing her little girl throwing some serious shade with her expression.
Next to the sassy shot of North's side-eye, Kim simply joked: "Mood."
The Keeping Up With the Kardashians star was recently asked about how motherhood feels to her, and she had the sweetest answer.
Responding to a fan on Twitter, Kim said it was "beyond what I imagined in the best way possible".
