Heard, 28, smiled as she draped her left hand—with her engagement ring on full display—across the back of Depp's neck. The Transcendence star, 50, looked casual in a tan hat and white T-shirt as he leaned against the car to smooch his fiancee. On the actor's left hand was his endearing man-gagement ring.

The couple's latest PDA outing comes nearly 10 days after they attended the 2014 Costume Institute Gala together, hand-in-hand.

Days later, they caught the famed Queen of the Night show at Simon Hammerstein’s Diamond Horseshoe at the Paramount Hotel on May 7. At the fun-filled show, an eyewitness described the couple as "gorgeous" and "super cool" to Us Weekly. Heard first caught Queen of the Night last month, and wanted to experience it again with her fiance, the source added.

Us confirmed the actor's engagement to his Rum Diary costar back in January. "She's a wonderful girl," he recently said on the Today show. "She's sharp as a tack. A Southern belle and sweet as can be, and very good for me."
