Scarlett Johansson and Sean Penn have parted ways. Speculation of a break up started after Johansson did not attend the Cannes Film Festival with Penn for his movie The Tree of Life. The oddly paired couple made headlines when they took a whirlwind trip to Mexico after being spotted getting flirty together during a lunch date in Los Angeles. They also attended the White House Correspondents Dinner party in Washington D.C together in April and had been spotted in a series of cozy outings in Los Angeles. No reason was given as to why they are no longer dating.
