Elsie Hewitt wants to hear what the actress has to say about Ryan and she has called on her to testify next month (October 2019), according to The Blast.
Hewitt sued Phillippe, accusing him of assaulting her and throwing her down a flight of stairs following their break-up. He denies the accusations.
Another of Phillippe's exes, Paulina Slagter, has also made it onto Hewitt's list.
Last month (August 2019), the actor attempted to block his ex-girlfriend from deposing Witherspoon, telling the judge overseeing the case his marriage had no relevance.
According to the outlet, Ryan also asked for any evidence of prior police reports filed against him and information about dietary supplements to be scratched from the proceedings.
Hewitt sued the actor for $1 million and alleged he abused drugs like "cocaine, ecstasy, psychedelic mushrooms, and steroids".
Phillippe accused his ex of trying to extort him with false allegations.
Earlier this summer, he lost his bid to keep Slagter from testifying in the case. Hewitt also shut down the actor's attempts to block her from obtaining police records.
