Sean Penn and Scarlett Johansson have reunited, this time for a late, cozy dinner at Hollywood’s celebrated Chateau Marmont.
The two, who jetted off to Mexico for a day together last week, greeted each other at the hotel restaurant with a hug. They were all smiles and chatted quietly for several minutes before moving from one table to a more private setting in the back corner.
Both dressed casually, Penn, 50, and Johansson, 26, appeared at ease with one another as they talked, smiled and remained focused on each other.
