The Free Guy actor captioned the sensuous photo of him sitting in a park in a white tank and khakis, "Summer in New York makes me sorry for the way I treated winter in New York."
The Gossip Girl alum, who shot the photo, accompanied it with sriracha sauce, pepper, and "Caution: Extra Spicy" emojis.
