Affleck, 45, was wearing a plaid suit with a white shirt, while Shookus, 37, was wearing a lacy black outfit and heels. David, 70, was dressed very casually, wearing a blue cardigan, off-white pants and sneakers.
While they were all outside walking together, Shookus reached out to hold onto Affleck’s arm.
Shookus and David have likely met before — Shookus is a producer on Saturday Night Live, which David hosted in February 2016. David’s daughter, Cazzie David, is also dating SNL castmember Pete Davidson.

The two have been spending time together on both coasts since, stepping out for coffee runs, casual breakfast dates and nights out. They recently vacationed in Maine together, and on Saturday night, the two were spotted cuddling up together at the U.S. Open in New York City.
Shookus was previously married to SNL colleague Kevin Miller and has one daughter with him. Affleck has three children with Garner — Violet, 11, Seraphina, 8, and Samuel, 5.
