Jennifer Lawrence, Emma Stone, Jessica Chastain and Saoirse Ronan by Ruven Afanador for THR November 15, 2017

Jennifer Lawrence had some advice for recent New York transplant Mary J. Blige on acclimating to life in Los Angeles. "Just make friends with your neighbors, like I did," Lawrence, 27, said to Blige, 46, before the start of The Hollywood Reporter's annual Actress Roundtable, held November 11 at Line 204 Studios in Hollywood. The mother! and Mudbound stars were meeting for the first time, but Lawrence is already good friends with fellow Oscar winner Emma Stone, 29. And three of the participants — Stone (Battle of the Sexes), Jessica Chastain (Molly's Game), 40; and Allison Janney (I, Tonya), 57 — worked together on 2011's The Help. And all seemed endlessly fascinated by the thick Irish accent of Saoirse Ronan (Lady Bird), 23, so much so that nearly everyone attempted their own Ronan impression before the hourlong conversation was over.
