Former reality television star Blac Chyna gave evidence on Thursday that she had no personal knowledge of anything Kim Kardashian, Kris Jenner, Khloe Kardashian or Kylie Jenner had said or done to harm her reputation.

Chyna was in the witness box for the third day in a Los Angeles court at the trial for her 100 million dollar (£77 million) lawsuit against the four Kardashian women that alleges they forced the cancellation of her show Rob & Chyna and damaged her celebrity status.
