Blake Lively and husband Ryan Reynolds told a federal judge Thursday that they will seek to dismiss Justin Baldoni’s defamation lawsuit. Attorneys for the two sides are due in court Monday for the first hearing on the megafeud between the two “It Ends With Us” co-stars.

Justin Baldoni is heard apologizing to his co-star Blake Lively in an audio message apparently sent to Lively amid production of their film “It Ends with Us,” long before the two stars launched into a legal battle that continues to play out in the public eye.

The film is just one of several projects the filmmaker could lose amid his growing fight with his ‘It Ends With Us’ co-star.
