Josh Brolin was photographed getting cozy with a new leading lady, Kathryn Boyd, in Rome on Sunday.
Boyd has reportedly worked as Brolin’s assistant, but their relationship looked much more than professional as they were spotted kissing and cuddling in the romantic city as they wandered the cobblestone streets and stopped at the famous Trevi Fountain.
A rep for the actor did not immediately respond for comment.
The Oscar nominee, who checked into rehab last November, is back at work: He’s in Italy to film Everest, a film about mountain climbers who met with disaster atop the peak in 1996, with Jake Gyllenhaal, Jason Clarke and John Hawkes.
