Jennifer Lopez and Ben Affleck are enjoying early fall in New York.

The couple were spotted packing on the PDA during a Sunday walk through the city, laughing, holding hands and even sharing a sweet kiss.

Lopez, 52, stepped out in a green-and-blue plaid maxi dress with a matching coat and aviators for the chilly weather. Affleck, meanwhile, wore a navy polo shirt, gray wool blazer, jeans and boots for the stroll.

The outing comes after a source told PEOPLE that the Gone Girl actor, 49, flew to NYC to support Lopez ahead of her performance for Global Citizen and Global Citizen's Recovery Plan for the World, a campaign to end COVID-19, on Saturday.

"Jennifer and Ben were apart for a few days earlier this week. They met up in N.Y.C. yesterday," the insider said. "Ben wanted to be by her side and attended the event. He watched her perform."

"They are always supportive of each other's careers," the source said of the stars. "Ben has to be in Texas to film this coming week."

Another source previously told PEOPLE that while the pair "have months of work coming up," they "plan on spending the holidays together" after their busy fall.

"They will both get a break. For Jennifer, Christmas is all about the kids," the source said. "She makes it very special for them. She loves Christmas."

The insider added, "This year, it will take some more planning since Ben wants to be with his kids too. They haven't made any specific holiday decisions yet and are still working it all out."

Affleck and Lopez engaged in 2002 and made headlines as "Bennifer" during their years together, even costarring in the films Jersey Girl and Gigli. The pair postponed their wedding days before they were set to walk down the aisle in 2003, and officially split by January 2004.

The stars rekindled their romance in April before going Instagram official in July for the singer's birthday. Affleck and Lopez made their red carpet return at the Venice Film Festival earlier this month.
