ScarJo Storms Out! Custody Negotiations With Her Ex Crumble After Tense Face-Off

Scarlett Johansson's custody war with her French ex has dissolved into a nasty public brawl, and Romain Dauriac's attorney told RadarOnline.com that it's HER fault!

“We are not sure what she was upset about and why she filed the divorce, but something must have happened during the discussions because she got up and walked out,” attorney Harold Mayerson exclusively told RadarOnline.com. “We are hoping she will come back to the negotiating table.”

Mayerson represents French journalist Dauriac, who married Johansson, 32, in October 2014 after welcoming daughter Rose Dorothy.

As RadarOnline.com has reported, Mauriac's attorney claimed Johansson’s busy acting and travel schedule doomed their marriage after only two years.

“She was through with the relationship,” Mayerson told RadarOnline.com. “Both partners wanted to move on as quickly and as painlessly as possible.”

The growing animosity apparently has nothing to do with money, however. The two are reported to have an “iron clad” prenup.

Instead, it all comes down to what will happen to their two-year-old daughter. Dauriac wants primary custody, and would like to take Rose Dorothy back to his home country of France. Johansson is arguing for residential custody, and for the child to live with her instead.

“It is indeed unfortunate, especially for our daughter, that Scarlett filed in court and made our personal differences so public,” Dauriac said in a statement given to RadarOnline.com. “I would implore her to withdraw her action promptly and to go back, as uncomfortable as it might be, to the negotiating table."
