Scarlett Johansson may not be single for long after her split with Sean Penn — the stunning actress has been spotted cozying up to “Hangover” star Justin Bartha.
Johansson, who split with Penn a month ago, attended a preview of off-Broadway’s “All New People,” in which Bartha stars, on Saturday, and the pair were photographed together backstage.
Spies said Johansson and Bartha later seemed “completely engrossed in each other” during a cast dinner also attended by playwright Zach Braff and actress Heather Graham at Café Un Deux Trois.
One witness told us, “There were about 15 people at the table, but Scarlett and Justin sat next to each other and talked all night.
“They seemed pretty fascinated with each other and only talked to each other,” the source said. “It looked sometimes flirty, but also they seemed to be involved in a deep discussion.”
While some sources insist 26-year-old “Lost in Translation” star Johansson and Bartha, who turns 33 today, are just good friends — exactly what they previously said about ScarJo and Penn — she and Bartha were also reportedly seen “flirting up a storm” at Karaoke Boho here on Saturday.
She split with Penn, 50, after five months in June. Bartha ended a two-year relationship with Ashley Olsen in March.
Meanwhile, Scarlett’s ex-husband, Ryan Reynolds — recently linked to Charlize Theron — hung out with a brunette stunner at the Jimmy rooftop bar at the James Hotel in SoHo on Tuesday night.
The pair were with two other friends, but another witness told us, “I definitely got the vibe that Ryan had eyes for the brunette. All four hung out the entire time together, but there was definitely chemistry between the two them. Lots of laughing and all smiles.”
Reps for Johansson and Bartha didn’t get back to us. Reynolds’ rep had no comment.
