Blac Chyna joins Kardashian-Jenner clan to celebrate Khloe's birthday

Blac Chyna was embraced by the Kardashian-Jenner clan as they played a string of arcade games to celebrate Khloe Kardashian's birthday on Monday night (27Jun16).

Blac, 28, divided the famous family when she struck up a romance with Rob Kardashian at the beginning of the year (16), as she was previously engaged to his half-sister Kylie Jenner's love interest Tyga, with whom she has son King Cairo, three. Blac and Rob, 29, surprised people even more when they announced their engagement in April (16), followed by the news that the model was expecting their first child together.

Khloe, her sister Kim Kardashian and their mother Kris Jenner all voiced their shock and initial disapproval on reality show Keeping Up with the Kardashians, but it seems they've firmly put their differences aside now as they united on Monday.

Kim, 35, shared a moving Boomerang photo on Instagram of her and Blac playing air hockey together, captioning the shot: "Slip n slide with@blacchyna," and even Kylie, 18, was present, as she posed for a picture with Kim in front of a colorful wheel, writing: "my mom and me@kimkardashian".

Blac appeared thrilled to be spending time with her fiance's relatives as she too took to Instagram to post a cute photo of her and Kris, 60, beaming at the camera.

"So much fun with Mama@krisjenner," she captioned the moment, followed by another black and white photobooth picture of her, Rob and Khloe, 32, pulling silly poses.

"Happy Birthday@khloekardashian," Blac wrote.

Kylie and Tyga, 26, were believed to have parted ways in May (16), after their relationship began when the reality star was just 16. It seems as though they've reunited though, as the musician posted a photo of his former flame on his bed online last week (end24Jun16), and Kylie stepped out in a jumper with a giant tiger on the front on Sunday (26Jun16).
