Blac Chyna Wants to Get Her Hands on Ryan Seacrest's Emails With Kim Kardashian and Kylie Jenner

Blac Chyna is demanding Ryan Seacrest hand over personal emails he exchanged with Kim Kardashian, Kylie Jenner and Kris Jenner as part of her nasty legal battle with Rob Kardashian.

According to court documents obtained by The Blast, Chyna is seeking to grill Seacrest under oath during a deposition as part of her lawsuit over the cancellation of her E! reality show "Rob & Chyna."

Chyna sued Rob and his family accusing Khloe, Kris and Kylie of interfering with the show and causing producers and the network to cancel the show, which allegedly caused her substantial damages.

The Kardashians have denied all allegations of wrongdoing and have demanded the suit be tossed.

In her newly-filed docs, Chyna accuses Seacrest of refusing to sit for a deposition in the case even though he was an executive producer on "Rob & Chyna." She believes he has knowledge that will help her build her case against Rob and the rest of his family.

Chyna wants the court to sanction Seacrest for failing to appear and order him to be deposed ASAP.

The case is ongoing.
