Scarlett Johansson’s date at Reese Witherspoon’s wedding: Sean Penn

That’s what stirs up rumors about a possible romantic relationship between the two actors.

Sean and Scarlett have been spotted many times together, sometimes very close to each other, but Johansson has always denied the news that she makes a pair with Sean Penn.

Yet both stars were present at Reese Witherspoon’s marriage, according to Popeater.

“Turning up at a wedding with your boyfriend is definitely a huge statement, especially that wedding,” a source tells the site. “What it’s doing is announcing to the whole of Hollywood that they are serious.”

No details have been released yet. It’s still unknown if the actors came together or not. However, it’s at least a strange coincidence.
