In a series of new photos from a Fourth of July bash, the couple are seen smiling, smooching, laughing – and playing in a dunk tank with Lively’s family in New York.
In one steamy photo, Reynolds, 35, pulls Lively, 24, in close for a kiss while she wraps her arm around his neck and balances a drink in the other hand.
Lively wears a patriotic blue and white polka dot swimming suit, while Reynolds is pictured in a white tank top and khaki pants in some shots and in a pair of loose, blue swim trunks in others.
