Kim Kardashian's family and friends made sure that she had a day to remember when she marked her 40th birthday on Wednesday.
But the Skims founder's sweetest gift came from her two-year-old daughter Chicago.
The proud mum took to Instagram to share a cute video of the toddler singing happy birthday to her famous mum while out on a trip to the park.
In the footage, Chicago enthusiastically sang happy birthday over and over again, dressed in a sweatshirt.

The fun dance show featured on Keeping Up with the Kardashians Kim's Birthday Special, which aired on Wednesday.
Meanwhile, Kim's husband, Kanye West, paid a public tribute to his wife on Twitter, sharing a sweet photo of them that had been taken shortly after he proposed to her in an empty baseball park in San Francisco.
He wrote: "Been doing empty stadiums. Happy 40th birthday!! I love you so much."
Kim's sisters and momager, Kris Jenner, also shared photos of the birthday girl from over the years on social media to mark her big day.

Kim spent her birthday surrounded by her family. The KKW Beauty mogul shares children North, Saint, Chicago and Psalm with Kanye, and has enjoyed spending quality time with them during the pandemic.
The star also admitted to struggling at times when it came to homeschooling her oldest two children.
During an appearance on The View earlier in the year, she said: "Being at home with four kids – if I ever thought for a minute that I wanted another one, that is out the door. It's really tough. It's really tough."

"It's been tough juggling it all, and you know, you really have to put yourself on the back burner and just focus on the kid."
