The handsome Rum Diary costars, who have been dating since 2012, attended The Art of Elysium's 7th Annual Heaven Gala presented by Mercedes Benz and sponsored by Peroni Nastro Azzurro on Saturday, Jan. 11 in Los Angeles.
Even though the 50-year-old actor did not walk the red carpet, the beautiful duo posed for photographs inside the event.
Depp sported a dark suit and covered his light locks with a Fedora, while Heard, 27, wore a black-sequined long dress and bright red lips.
The duo was spotted at the front table by the stage and Depp had his arm around his ladylove as they listened to Evan Rachel Wood perform "What's Going On?" Heard also held her beau's arm during the performance. The cute pair laughed and smiled throughout the performance and looked "so in love."
Additional celebs in attendance at the pre-Golden Globes bash included Nina Dobrev, David Arquette, Ali Larter, Joe Manganiello, Anna Kendrick, Kate Bosworth and Michael Polish, Amy Smart and Carter Oosterhouse, Camilla Belle, Busy Phillips, Jennifer Morrison, Jamie-Lynn Sigler and James Marsden.
