Leonardo DiCaprio [1] and Nina Agdal are still going strong! The couple has been keeping a low profile as of late, but on Sunday, the two were photographed holding hands while strolling through Central Park in NYC. Leo kept things casual in his signature newsboy cap [2] and sunglasses, while Nina also did the same in a puffy coat and sneakers. Leo recently announced his investment in LoveTheWild [3] (a sustainable food company that sells farm-raised frozen seafood meals), and Nina currently graces the cover [4] of Maxim's March issue, so perhaps they've just been busy with work commitments.
