And in the case of Scarlett Johansson and Sean Penn, it looks like it may have been a bit sooner than expected. The couple’s fast-tracked romance – which began just a few short months after Johansson split from husband Ryan Reynolds – has ended, according to People.com. Penn’s relationship with the actress first became public when they dined in Los Angeles on Feb. 28 – with Johansson’s foot resting firmly in his lap. The outing was quickly followed by a trip to Cabo San Lucas, and in late March, Johansson, 26, brought him as her date to Reese Witherspoon’s wedding.
