Jennifer wrapped up in a black coat and beige trousers and accessorised with a pair of tan gloves, a neck scarf and oversized sunglasses.
Meanwhile, 71-year-old Robert looked like the life of the party as he handed out large glasses of red wine to cast and crew members.
In the comedy biopic, Jennifer plays single mum and successful businesswoman Joy Mangan.
The Hunger Games star looked happy despite the freezing temperatures following her romantic weekend with British musician Chris.
According to US Weekly, Jennifer and Chris met up at Tavern On The Green where they shared a romantic brunch.
An eyewitness, who saw them at the restaurant, said they arrived separately.
Jennifer got their first and “waited in her car for a little bit before moving into the restaurant with her bodyguard. Then Chris got there. They made it a quick lunch. She had a roast beef sandwich and he had eggs Benedict”.
According to the observer, the two “were whispering to each other and giggling”.
After their meal, the loved-up pair left the restaurant holding hands and went for a stroll through Strawberry Fields, Central Park’s 2.5 acre memorial to John Lennon.
They then reportedly spent the night together at the Carlyle Hotel before they both arrived separately at Teterboro Airport in New Jersey and jetted off on a private plane.
