Reese Witherspoon will be called to testify about Ryan Phillippe in the lawsuit brought against him by his ex-girlfriend.
Elsie Hewitt is suing the 44-year-old actor - who she dated from April to July 2018 - over an alleged incident at his home two years ago, where she claims he was violent towards her during an argument.
The Guess model alleges she went to Ryan's house with a friend to pack up her things after a party, which the actor had left earlier after "being ignored" by her, when a physical altercation ensued.
And she has put Oscar winner Reese, 43, - who has 19-year-old daughter Ava and 15-year-old son Deacon with Ryan - to testify against the actor, according to The Blast.
The trial will begin on October 15 and Ryan previously attempted to keep Reese - who he divorced in 2007 - from being called to testify, with his lawyers arguing in court filings that she is not relevant to the case.
