(Cover) - EN Showbiz - Scarlett Johansson has sparked a new couple alert.

The 26-year-old actress was reportedly seen getting cosy with 50/50 star Joseph Gordon-Levitt in New York City last month.

Us Weekly claims that the pair were very close with each other but it was not the first time.

"They were kissing," an eyewitness told the publication. "They were very lovey."

The pair were also apparently seen having dinner together at Hundred Acres in the SoHo area of the Big Apple in late July.

A source said that Scarlett and Joseph, 30, had been "discussing a project for a while [but] have never kissed."

But another insider claims that they are spending time together but are trying to keep things quiet.

"They first met about a film they wanted to do together, but it's gone beyond that now," the insider said.

The pair are said to be having fun but "nothing serious" is going on.

Scarlett divorced from Ryan Reynolds last December and had a brief fling with Sean Penn.

Joseph has been linked to Evan Rachel Wood and Devon Aoki in the past. (C) Cover Media
