Kim Kardashian West is peacemaker between Kylie Jenner and Blac Chyna

Kim Kardashian West played peacemaker between Kylie Jenner and Blac Chyna.

The 35-year-old beauty intervened to call a truce between Blac and her 18-year-old half sister – who is currently dating the 27-year-old model’s ex-fiancé Tyga, with whom she has three-year-old son King Cairo – in order to ease tensions after her Rob Kardashian proposed to the make-up artist.

Speaking to TMZ about Kim’s interference, a source close to Blac claimed she received a phone call from the ‘Keeping Up With the Kardashians’ TV personality asking her to resolve the dispute over both matters,prompting her to visit the brunette star’s home to discuss the matter.

Blac took heed of the advice from Kim and called Kylie in a bid to thaw relations between them.

And the pair were able to use social media to end the speculation of an ongoing feud, by insisting they are "best friends".

Kylie took to Snapchat on Thursday (04.21.16) with a selfie of her and her beau’s former lover on Snapchat, which was then shared on her Instagram account, although it has since been removed from the site.

Kylie wrote: "When we’ve been best friends the whole time (sic)."

Blac swiftly followed suit by uploading a string of pictures with the Kylie’s Cosmetics businesswoman; one of a face-swap and another mirror shot.
