Scarlett Johansson 'not dating Kieran Culkin'

Scarlett Johansson and Kieran Culkin are not dating, contrary to reports.

The two actors were first spotted together in Paris in mid-September. A week later, they were photographed strolling arm-in-arm in New York, sparking rumours that the two are in a relationship.

However, a source told Us Weekly that the two are simply friends from high school.

"She has never hooked up with Kieran," the insider said.

Meanwhile, another friend went on to address reports that Johansson is dating Justin Timberlake, claiming that the pair simply enjoy intercourse from time to time.

"[Johansson and Timberlake] hooked up several times over the years," the friend said. "They've always been fine keeping it just sex and friendship."

Johansson finalised her divorce from Ryan Reynolds in July.
