The are-they-or-aren't-they pair are back on, E! News confirms, after being spotted rocking out together to the sounds of The Rolling Stones during the band's surprise concert at the Echoplex in Hollywood last night.
Depp was also seen holding Heard's hand as he led her through the crowd.
Romance rumors between the celebs began last year when the duo began spending extra time together after costarring in The Rum Diary—and the fact that Depp bought his leading lady her own horse added to the hearsay.
However, the could-be couple continue to keep fans guessing about their status since neither star's camp has confirmed the relationship.
Heard was last linked to female photographer Tasya Van Ree, while Depp parted ways from French model Vanessa Paradis last June after 14 years together.
