Sean Penn and Scarlett Johansson Split

OMG Famous

And, just like that, it's over.

The strange relationship between Sean Penn and Scarlett Johansson -- which none of us ever wanted to fully accept as real -- is over.

People reports that the two are no longer dating, though they disappointingly have no other details about the split or what instigated it. Neither rep commented on the story.

The magazine mentions that Johansson was noticeably absent from the Cannes Film Festival, where Penn was promoting his "The Tree of Life." Johansson, who divorced Ryan Reynolds last year, has been in New Mexico filming "The Avengers."

While their relationship may have turned out to be brief, they certainly got their share of headlines out of it: they kicked things off with a flirty, footsie-centric lunch in Los Angeles; jetted to Cabo where they were called "like teenagers in love"; held hands for the first time at no less than the White House Correspondents' Dinner; and they went jogging with Owen Wilson.

But now that it's over, we're going to try to pretend all of it never happened.
