Actress Scarlett Johansson insists she isn’t dating Sean Penn!

Scarlett Johansson isn’t hooking up with Sean Penn. Reports earlier this week claimed the actress — who recently split from husband Ryan Reynolds — might be dating Penn after the pair were spotted dining together at Los Angeles hot spot Chateau Marmot.

“Scarlett first reached to Sean when she was planning to visit Haiti with Oxfam,” a source told Us Weekly magazine.

“She knew Sean was living there in a tent and turned to him for advice.

“Scarlett’s smitten with him.”

But Scarlett’s rep has spoken out to set the record straight.

“Scarlett and Sean are not dating – they have been friends for years,” the rep told E! News.

“Nothing more, nothing less. They have been talking over the last few months regarding Haiti Relief and Scarlett’s upcoming trip to Haiti as Oxfam’s Global Ambassador.”
