Scarlett Johansson and Sean Penn Have Split!

All good things must come to an end! After a short four months of dating, it seems that Scarlett Johansson and Sean Penn have gone their separate ways.

According to PEOPLE, ScarJo and Sean are no longer dating. Speculation that the former lovebirds (who flaunted their relationship all over town) had split up sparked when Sean flew solo at the Cannes Film Festival, where his new movie Tree of Life was featured. ScarJo was nowhere to be found. 

Their relationship, which began a few short months after Scarlett split from her husband Ryan Reynolds, became public late February when the two were spotted dining together in L.A. Rumors sizzled when they embarked on a trip to Cabo San Lucas together and their attendance at Reese Witherspoon's wedding in March pretty much confirmed and solidified the relationship.

No word on why the couple split - their reps have remained mum on the issue. 

Are you surprised ScarJo and Sean Penn broke up? Or are you more surprised they were ever a couple?
