The new couple were out and about on Sunday night.
Ben Affleck and Lindsay Shookus took their romance to the East Coast.
The new couple was spotted out in New York City on Sunday night following a dinner date at Mas Farmhouse. Affleck was casually dressed in a red T-shirt, faded black denim, a blue blazer and matching blue sneakers, while Shookus sported a pair of blue skinny jeans, nude-colored sandals and a black blouse.
Affleck's night out in the Big Apple comes just a few days after he celebrated his 45th birthday in Los Angeles with his three kids, Violet, 11, Seraphina, 8, and Samuel, 5, whom he shares with his ex, Jennifer Garner.
While we've yet to see Shookus hanging out with Affleck's kids, she did spend some time with his younger brother, Casey, earlier this month when he joined them for an evening at Hollywood's comedy club iO West.
"[Ben and Lindsay] are having fun together and are happy they are able to officially be a couple," a source told ET of the pair.
