Kim Kardashian and Blac Chyna pout and make up

They were sworn enemies, but now Kim Kardashian and Kylie Jenner seem to have warmed up to Blac Chyna, who was the guest of honour at Khloe Kardashian's birthday. Kylie's boyfriend, Tyga, is Chyna's baby daddy and the friction has been palpable, but apparently not any more.

Blac shared photos with "mama" Kris Jenner and her future sisters-in-law as they celebrated together, appearing comfortable, reports mid-day.

And it certainly wasn't one-sided, as Kim followed with her own mini clips of them dancing together in a video arcade — appearing to be BFFs once more.

Joining them was Blac's future mother-in-law Kris - and she's already calling her mama. Pregnant Chyna was positively glowing as she cuddled up to future hubby Rob throughout.
