Josh Brolin has been pictured kissing Kathryn Boyd.

The No Country for Old Men actor was seen smooching with the blonde, who has reportedly worked for him as an assistant, in Rome this weekend. According to People.com, the pair "wandered the cobblestone streets and stopped at the famous Trevi Fountain."

Josh, 46, has been single since his divorce from Diane Lane, his wife of eight years, was finalized last year.

The actor - who also had a stint in rehab November last year after a number of drunken incidents - in is in Italy working on Everest, about an ill-fated expedition up the world's highest mountain in 1996, which resulted in eight people's death when their team got caught in a blizzard. The movie will also star Jake Gyllenhaal, Jason Clarke and John Hawkes.

In preparation for the film, Josh and Jake went for a hike in the Santa Monica mountains, but things took a downward turn after they lost sight of their direction markers. "They'd started out in Malibu canyon and followed marked paths until they got to a rocky area where Jake wanted to climb. When they started back down the other side of the mountain, Jake kept insisting he knew the way but after an hour, Josh realized Jake had no clue."

Facing the prospect of darkness falling, temperatures plummeting and dangerous wildlife including coyotes and poisonous snakes attacking them, the pair appealed to the first people they came across, a Boy Scout troop, who helped bring them back down safely.
