Another new guy for ScarJo?

Scarlett Johansson was spotted making out with 50/50 star Joseph Gordon-Levitt in NYC last month. "They were kissing," an eyewitness tells the new Us Weekly, on stands Friday. "They were very lovey." 

It wasn't the first time Johansson, 26, and Gordon-Levitt, 30, hit the town together. The duo dined at Hundred Acres in NYC's SoHo area in late July. 

Although a source tells Us that Ryan Reynolds' ex and Gordon-Levitt have been "discussing a project for a while [but] have never kissed," another insider explains, "They first met about a film they wanted to do together, but it's gone beyond that now."

Still, Johansson's pal insists there's "nothing serious" going on between the stars.
