Kim Kardashian fans in tears over 'adorable' video of Saint kissing sister Chicago

Move over Kim Kardashian, Saint may have won over your legion of fans.

The mother-of-three melted hearts after she posted a string of videos showing her one-year-old son showering his baby sister Chicago with kisses.

Saint was all smiles as he hugged and kissed the newest addition to the Kardashian-West clan and revealed his sister’s secret nickname.

Taking inspiration from The Incredibles, he can be heard saying: “I’m hugging Jack Jack.”

Kim asks “who are you?” to which he replies: “Dash.”

Saint then reveals that he also has a nickname for his mum, who he calls Elastigirl.

Another video shows Kardashian laughing at the camera as Saint shouts: “Jack Jack is licking my finger.”

She captioned one of the clips: “He loves his sissy.”

Fans were in awe of the sibling love with one tweeting: “Kim’s snap with Saint & Chi are sooooo cute! I hope the west family are the incredibles for Halloween. The way Saint named everyone to be one of them is super cute!”

Another was left in tears, posting: “Saint hugging the s*** out of Chi has me sobbing.”

A third wrote: “OMG SAINT CALLING CHI JACK JACK WAS THE HIGHLIGHT OF MY EXISTENCE!!!!! @KimKardashian.”

Kardashian welcomed Chicago, or Chi, via a surrogate in January. She is the reality TV star’s third child with husband Kanye West. They also have five-year-old daughter North together.

Kardashian recently revealed Chi’s middle name on Instagram. Alongside a mother-daughter selfie she wrote: “Chi Noel.”

Fans were quick to note that Noel is Kardashian’s own middle name.

Chi was the third Kardashian baby to be born this year after Kylie Jenner gave birth to daughter Stormi with Travis Scott and Khloe Kardashian welcomed daughter True with Tristan Thompson.
