Kim Kardashian has revealed her son Saint has lost his first tooth - and wrote a cute message to the Tooth Fairy in the process.
The reality TV star, 42, took to her Instagram Stories to share the news about her seven-year-old, who she co-parents with ex-husband Kanye West.
She showed off the note the youngster wrote as he pleaded with the Tooth Fairy to send something other than money - Roblox!
Kim wrote: "lost his 1st tooth!," and revealed how Saint penned asking if he could "please have Robux" instead of money, referring to the virtual currency of the popular gaming app Roblox.
Saint's note continued: "Please check bag."
On the next slide, the SKIMS founder showed off a $2 note and gold glitter alongside a Roblox gift card, showing that Saint had got his wish. She joked: "North says the tooth fairy writes in cursive which I haven't done in 15 years lol."
Her next clip showed a trail of the glitter leading up to the youngster's bed as she captioned it: "The tooth fair [sic] was here."
On the same day, Kim and Kanye's daughter Chicago celebrated her fifth birthday. She labelled her child her "twin" in a sweet tribute post on social media.
In a series of adorable photos of the pair together, Kim was seen pouting and laughing as she admitted she "can't believe" her second youngest child is already five years old.
Kim opted for a black boucle teddy tracksuit from her Skims range for the snaps and went makeup free with her hair tied in a sleek updo with long strands framing her face at the front.
Chicago meanwhile was dressed in a matching mini-me outfit to her mum's and had her hair styled in space buns with two plaits at the front.
Alongside the uploaded, Kim wrote: "My twin. Happy 5th Birthday. I really can’t believe you’re 5! I’m so so proud to be your mom, it’s the best feeling in the entire world. You are the cuddliest sweetest silliest most independent caring girl in the whole world and I just love you so much!"
Other members of the famous family, including Kris Jenner, also shared public birthday messages to the youngster.
