Since starting her relationship with Kanye West, Kim Kardashian has gone through a lot of changes. She’s refreshed her wardrobe, her career, and even her social circle, adding a bevy of new beauties to her already extensive group of friends. One such pal is Blac Chyna. She and the Kardashian sisters seem to be attached at the hips these days, whether getting in a workout together or having a cozy dinner with their significant others in L.A.

So what do we know about Kim’s new pal?

1. She’s also engaged to a rapper.

Blac Chyna met Young Money rapper Tyga back in October 2011 and started dating him shortly thereafter. The former stripper even stars as the love interest in the video for his mega-hit “Rack City.” The two announced their engagement the following year.

2. She’s a mom, just like Kim!

Tyga and Chyna welcomed their first child, son King Cairo Stevenson, on October 16, 2012. The couple both got tattoos to commemorate their son’s birth.

3. She’s a Calabasas resident.

After baby King was born, Tyga and Chyna moved into a luxe mansion, purchased for a cool $6.5 million, in the Kardashians’ stomping grounds.

4. She’s Amanda Bynes’ style mentor.

Remember when Amanda Bynes bought all of those wigs and pierced her face? That was all an attempt to look as lovely as Chyna, according to the troubled starlet.

5. She’s a social media star.

Between her 1.3 million Instagram followers, her 180,000 Twitter devotees, and the droves who turn out to check out the bootylicious pics she posts on her website, Chyna, much like her pal Kim, knows a thing or two about the art of a well-placed selfie.
