Tyga and Blac Chyna's son King Cairo is growing up so fast, and he just turned one year old this past weekend. Cairo's hip-hop parents, who love to party, did it big when it came to their son's first birthday celebration. Among the guests who showed up, Kim Kardashian's appearance at the party surprised everyone the most.

Blac Chyna, the girlfriend of YMCB rapper Tyga, has been spotted out with Kardashian in the past few weeks, along with her other famous friends. Chyna and the reality star have been snapped by paparazzi several times together.

The hip-hop couple hired a Disney character crew to make the party more fun and enjoyable for their adorable son. The Disney-themed b-day bash got even hotter when Chyna's new girlfriend Kim Kardashian showed up to the party to spend a day celebrating at the house party. Other guests such as Kourtney Kardashian and her baby Penelope and rapper Lola Monroe also joined Cairo's birthday celebration.

"Brought Disneyland to the house for @kingcairo 1st bday!! #KingSh --," Tyga wrote on his Twitter.

While the party was going on, Blac Chyna posted a photo on her Instagram with a caption reading, "Party time... Kings 1st Birthday. Today ! I'm a excited Mommy." The former stripper also uploaded several more photos from the event, including a picture of Kim K wearing a mini mouse hat.

After spending a fun time with the Disney characters, King Cairo got to open some awesome birthday gifts with his parents right by his side. The baby boy got a mini-sized Ranger Rover, which was given to him by the Kardashian family.

Chyna posted a video of her driving around her son's extravagant gift on Instagram, saying "OMG I had to.... thanks from the Kardashian Fam!"

It seems that the one-year-old baby King certainly had an unforgettable, extraordinary birthday bash.
