Blake Lively and Ryan Reynolds 'are in it together' during the legal battle with Justin Baldoni, a source tells PEOPLE, and 'they will get through this as a team.'

Justin Baldoni and Blake Lively have attacked each other in court—and in the press—since filing competing lawsuits over treatment on the set of "It Ends With Us."

Baldoni then fired back with a $400 million countersuit in January this year, taking aim at Lively, her husband Ryan Reynolds and their publicist for allegedly seeking to destroy his reputation, while also suing the New York Times for publishing her lawsuit to the public.
