"They also shared a kiss during the party," a source said about Gaga and Carino, who first stepped out together this past February after the "Bad Romance" hitmaker split from fiance Taylor Kinney in July.

In A Star Is Born, a remake of the original 1937 film, Gaga plays a small-town girl hoping to make it big, while Cooper, who is making his directorial debut with the film, plays an alcoholic has-been rock star who helps to advance Gaga's character's career.

The wrap party marked a night out for Cooper and Shayk, who welcomed their first child together, daughter Lea De Seine Shayk Cooper, in April.
