They were spotted at the 14th Annual Author's Night to benefit the East Hampton Library.
Hilaria, who just gave birth to their fourth child back in May, looked gorgeous in a soft pink and white ensemble that she paired with so,e flip flops. Alec opted to wear a black polo and khakis.
The couple promoted their individual pieces of literature while at the event.
They also exhibited some major PDA as the evening went on, as the two enjoyed a passionate kiss while signing copies of their books.
Alec and Hilaria have experienced quite the whirlwind journey with each other. They met in August 2011, married in June of 2012, and eventually had four kids together. So how do they keep the romance alive amid all the chaos? "We spend a lot of time together. When the babies are sleeping, we always spend time together,' she said on Today back in late July. "We just like each other. We're very different. We're extraordinarily different, the complete yin and yang, but we like each other."
