Kim Kardashian West has sent a birthday message and shared a video tribute to her daughter North, now four.
The 36-year-old reality TV star took to her official website and app to wish her "mini me" daughter North a happy birthday on Thursday and admitted she is amazed at how quickly time flies.
She wrote: "Happy birthday to my mini me!
"I can't believe you are 4 already. I love you so much, Northie!"
Kim - who also has son Saint, 18 months, with husband Kanye West - also posted a video montage of herself and North, which included a number of old clips.
In one, the 'Keeping Up with the Kardashians' star told her daugher: "Are you not going to get any bigger? You're not going to get any taller. I want you to stay little forever, OK?"
In another clip, North told her mother: "I love you so much."
Kim replied: "Well, even when you're big, you're gonna be so nice to me?"
North said: "Yeah."
The clip also featured a number of Kimojis based on the little girl.
