The mother-of-one, who is engaged to Rob Kardashian and expecting their first child together, was rumoured to have been frozen out of the famous family after they didn't approve of Rob's new relationship and the speed of its progression.
Chyna and Rob started dating in January, announced their engagement in April, and revealed their pregnancy news on Instagram in May.
Chyna (28) shares three-year-old King Cairo with former fiance Tyga, who is in an on-and-off relationship with Rob's younger half-sister Kylie Jenner - and the Kardashian/Jenners reportedly felt the relationship would cause too much friction in the family.
It also emerged in a recent episode of the reality show Rob had angered his sisters - Kourtney, Kim, Khloe, Kendall and Kylie - after they found out about his engagement and pregnancy news on social media rather through their brother.
Now, it appears Chyna has been welcomed into the fold, as her attendance at Khloe Kardashian's 32nd birthday party on Monday was filmed for an upcoming episode of the reality series.
Meanwhile, in a preview of the next episode, Kris Jenner is seen praising her son Rob and his new relationship, and gushes about her new daughter-in-law to-be, Us Weekly reports.
"Just being with them, and hearing what they had to say, and seeing how in love they are, is amazing,” she says in a clip of the E! show. "I said 'Look, I just want Rob to be joyful, happy and productive'. And he goes, 'Mom, I'm really happy. This is what I want.'
"He's a grown man and he needs to make his own decisions, and I need to let go a little bit," she adds.
Hinting at the family's previous reluctance to accept Chyna as a member of the family, Kris explains that she hopes her other daughters will follow in the footsteps of Kylie, who has accepted her brother's wife-to-be.
"It makes me so happy that Kylie was able to be so mature and sit down with her brother and Chyna and really get some of the past issues talked about," she said on the show. "The next step, I think is really for my other kids to follow in Kylie's footsteps."
Rob and Chyna are already in the process of documenting their whirlwind relationship for their own docuseries for E!, which is tentatively titled Rob & Chyna and is set to air later this year.
