Whatever their on-screen romance, the co-stars in the movie adaptation of Colleen Hoover’s novel It Ends With Us were reportedly far from cozy. On Monday, TMZ obtained a video that appears to show Blake Lively and Justin Baldoni (who also directed the film) embroiled in a disagreement on set, with Page Six now reporting that the lead actors watched the premiere from two separate theaters in New York. Lively reportedly wasn’t the only one uncomfortable working alongside her male co-star. “None of the cast enjoyed working with Justin,” one person told Page Six. “They certainly didn’t talk to him at the premiere.” The overall tension’s even thought to have gotten bad enough for Baldoni to consider not directing a sequel—though curiously, he’s previously said he thought Lively would do a better job.
