Saint West declined kissing his mother Kim Kardashian West in favour of playing around with a Snapchat filter.

The 'Keeping Up with the Kardashians' star's two-year-old son - whom she has with husband Kanye West - decided he'd much rather play around with the app's features than show his famous mom anymore affection on Tuesday night (07.08.18).

In the clip shared on her Instagram Story, the 37-year-old beauty - who also has North, five, and seven-month-old Chicago with the rapper - told Saint: ''Give me a kiss'', after he asked if he could use one of the many animal filters.

But he cheekily refused,and said: ''No. I just gave you a kiss to you.''

Startled Kim then said: ''No? What? You already gave me a kiss, I can't get another one?'', before pair then both donned the dog filter.

The cute video was posted hours after Kim shared a picture of Saint with his baby sister Chicago, and revealed the siblings are ''inseparable''.

She captioned the cute photo of the tots: ''These two are inseparable #Chi #Saint (sic)''

Meanwhile, the reality star recently admitted she doesn't like Chicago's name.

Kim agreed to call her youngster child, whom was born via surrogate, Chicago to pay homage to Kanye's hometown, but she admitted she's not really a fan of the moniker and always shortens it to ''Chi'' - pronounced ''shy'' - because it doesn't ''flow.''

Taking to her website KimKardashianWest.com, she spilled: ''Chicago just looks really long to me and doesn't flow, so I call her Chi. That's it, she can decide later if she wants to be called Chicago or Chi.

''But like she's so girly. When she first came out I was like what do we name her? It was the hardest decision ever and I could not think of a name.

''All the other names we had for her, we were going to name her Rei and spell it R-e-i for Kanye's dad Ray and she doesn't look like a Rei. We were going to call her Jo for Mary Jo and have it be Jo West. She doesn't look like a Jo.''
