About a month ago, Scarlett Johansson and Sean Penn seemed as cozy as it gets at the White House Correspondents’ Dinner. Now People magazine is reporting that the couple has split.

Citing an unnamed source, People says Johansson, 26, and Penn, 50, have ended their relationship, which began earlier this year following Johansson’s divorce from Ryan Reynolds. No reason for the break-up was given and neither rep for the actor has confirmed the split.

Could this be true? Has the ScarPenn situation ended as rapidly and surprisingly as it began? Stay tuned.
