(Cover) - EN Showbiz - Scarlett Johansson is rumoured to be dating Justin Bartha.

The stunning actress split from husband Ryan Reynolds last year and they are now divorced. She embarked on a short relationship with Sean Penn after the breakup, but that ended earlier this year.

She's now been spotted enjoying a lengthy conversation with Justin, who is single after his romance with Ashley Olsen ended. Scarlett went to see Justin's play All New People open in New York on Saturday, and was pictured with the actor backstage. She also went to a dinner for the cast that evening, during which the pair only had eyes for each other.

"There were about 15 people at the table, but Scarlett and Justin sat next to each other and talked all night," a source told New York Post.

"They seemed pretty fascinated with each other and only talked to each other. It looked sometimes flirty, but also they seemed to be involved in a deep discussion."

Scarlett and Justin further fuelled the speculation when they were seen enjoying some flirty fun at a karaoke bar in the city.

Neither of their representatives have commented on the claims. (C) Cover Media
