Scarlett Johansson and Joseph Gordon-Levitt dating rumors

Ryan Reynolds’ ex-wife and the 50/50 star were reportedly seen making out last month in New York .

“They were kissing,” an eyewitness tells Us Weekly. “They were very lovey.”

According to a source cited by the magazine, the two have been “discussing a project for a while [but] have never kissed.”

However, it seems that the nature of their relationship went beyond being strictly professional.

“They first met about a film they wanted to do together, but it’s gone beyond that now,” adds another insider.

Apparently, this wasn’t the duo’s first outing as they had been spotted dinging together at NYC’s Hundred Acres back in July.

But according to close friends of the actress, she and Gordon-Levitt get along well and share good times together, but there’s “nothing serious” going on between them.

Scarlett, 26, divorced actor Ryan Reynolds in December 2010 and had a brief relationship with Sean Penn. Joseph, 30, has been linked to Evan Rachel Wood and Devon Aoki in the past.
