After a whirlwind romance, Scarlett Johansson and Sean Penn have reportedly broken up, a source tells People Magazine.

While a reason for the breakup is unknown, speculation began that Sean and Scarlett were rocky when the pair didn’t attend the Cannes Film Festival together.

The split also comes days after reports surfaced of Sean partying late into the night with a blonde and brunette at his hotel in Cannes.

The closest thing Penn, 50, and Johansson, 26, did to publicly confirm their romance was attend the White House Correspondents Dinner together hand in hand back in April.

Scarlett has been busy filming The Avengers in New Mexico while Sean was in the French Riviera premiering Tree of Life. Perhaps scheduling did the couple in?
