The couple were spotted attending The Rolling Stones' concert in Los Angeles together. At the concert, which was also attended by stars like Gwen Stefani, Owen Wilson and Bruce Willis, Depp was seen casually holding Heard's hand as he led her walking through the crowd.
Representatives for both parties haven't commented, but a source said that Depp and Heard hinted at the possibility that the relationship was on again, reported Aceshowbiz.
"Johnny and Amber were really touchy-feely when they arrived in a limo. They spent the night hand-in-hand and Johnny was really keen to introduce her to his mates," a source said.
Heard allegedly left the 49-year-old actor last February for a French model Marie de Villepin.
From his former relationship with Paradis, Depp has two children, 13-year-old Lily-Rose Melody Depp and 10-year-old John "Jack" Christopher Depp III.
