The pair's outing comes after Eisner shared a rare photo of Olsen earlier this month.
Ashley Olsen is enjoying quality time with her boyfriend, Louis Eisner. The 35-year-old actress was photographed out on a date night with the painter in New York City on Saturday.
Olsen looked chic in a black ensemble, which she paired with black sandals and a matching black bag. She held onto Eisner's arm outside French eatery Balthazar, where they met up with some friends. Eisner, 32, looked casual in a white shirt and jeans, and appeared to be taking a phone call after their meal.
Olsen's outing with Eisner comes just over a week after the artist made headlines by sharing a candid photo of his girlfriend. The former Full House star, who retired from acting and stayed out of the spotlight for the most part, was seen enjoying a hike with a beverage in one hand and a machete in the other.
Eisner and Olsen have been together for several years; they were first spotted together in October 2017, before being snapped arm-in-arm in August 2018.
They sparked engagement rumors the following year when Olsen was seen wearing a ring on that finger after dining at an Italian restaurant in Los Angeles' Pacific Palisades neighborhood, though she's never commented on their relationship.
