Disturbing footage posted online showed the "Chopsticks" rapper getting kicked in the face and having his chain allegedly stolen.
The situation was enough to put him in the hospital, where the 19-year-old appeared slightly swollen with stitches on the left side of his face.
A fight broke out earlier in the day with another up-and-coming rapper named Lil Tjay. Both squads erupted outside a Saks store which then led to an all out battle on the streets of NYC. A website claimed that Lil Tjay had nothing to do with YBN getting jumped later on in the evening, however.
Chyna, 30, appeared unbothered by her ex flame's drama the day after it happened. The two began dating in February of 2018 before reportedly calling it quits months later in June.
She spent her day sharing a ton of pics and videos on her social media, including one of her mimicking Marilyn Monroe.
Chyna also posted two Instagram Stories of her getting a little too excited over her friend making her a healthy salad.
Do you think Chyna simply doesn't care about what happened to YBN? Sound off in the comments.
