It's a familiar story when it comes to the Kardashians and the women who at one time or another consider them friends: Somehow, the sisters frequently find themselves in relationships with the men of their current and former friends.

In 2013, Blac Chyna became a brand new BFF to reality TV starlet Kim Kardashian. This is important, because Kim K was already hot and heavy with rapper Kanye West, by whom the eldest Kardashian sister had North West in June 2013. Why is this important? Because in addition to her friendship with Kim Kardashian, Blac Chyna is also close to fellow former stripper turned model and video vixen Amber Rose. Amber Rose is, of course, an ex-lover and muse to West. Despite seeing her friends play musical chairs with their exes — Amber Rose briefly dated Kim K.'s former beau Reggie Bush — perhaps Blac Chyna thought she would evade the madness.

Well if so, she thought wrong.

Although their 3-year romance produced a son, King Cairo, Chyna and Tyga broke up in 2014. Their Tyga quickly moved on to dating Kylie Jenner, who he met when she was just 14. Despite the many raised eyebrows, both Tyga and Kylie began to date while she was a minor, choosing to make their relationship official once she turned 18.

Although Blac Chyna was allegedly heartbroken by Tyga deciding to date Jenner, she's since moved on Jenner's older brother, Rob Kardashian. Although, there was a bit of awkwardness at first, as evidenced by this clip from the Rob & Chyna reality TV show where she ran into her ex and Kylie Jenner.

Rather than make a fuss, Chyna admitted she decided to be the bigger woman because if she does marry Rob, Kylie will become her sister-in-law. And if Tyga sticks around and marries Jenner, they'll go from exes to in-laws.
