Ashley Olsen has been spending time with renowned artist George Condo, and the pair's New York outings have sparked rumours of a new relationship.
The fashion designer, 30, and the 59-year-old were dining at celebrity hotspot Balthazar, and an onlooker told the New York Post that "it was obvious something was going on [between them]."
"They were holding hands and snuggling," they added.
Another source told People magazine that they were in a corner booth usually reserved for couple because "it's a cosy little spot".
Skarstedt Gallery, who represents George, declined to comment.
It's not the first time the pair have sparked speculation of a romance, having been spotted at the Mercer Hotel together earlier this summer.
However, both of their representations revealed it was a business meeting – George, who split from his wife of 26 years in 2015, has previously worked with Ashley and her twin sister Mary-Kate's fashion house The Row.
Earlier this year, the artist sketched The Row's New York store, and the artwork was shared on the brand's Instagram.
Ashley was last linked to director Bennett Miller, 49, until their called time on their relationship earlier this year.
Her twin sister Mary-Kate, meanwhile, tied the knot with Olivier Sarkozy, 47, in November of last year.
