Kylie Jenner testified Monday that she expressed concerns to her brother Rob Kardashian about his new girlfriend and soon-to-be reality TV co-star Blac Chyna, because she had heard Chyna had a tendency to abuse drugs and alcohol and become violent.
"I felt it was my duty to express my concerns, but ultimately it was up to him," Jenner, now 24 and a teenager at the time, said from the witness stand at a Los Angeles trial. She said her brother didn't heed her warnings, and continued with the relationship.
