The actor was spotted celebrating with locals after his band's concert in Horsen, Denmark, on Wednesday. Depp, 52, looked relaxed as he mingled with a group of people outside of a hotel bar.
The actor stayed out until the early hours of the morning following his Hollywood Vampires show.
"[Johnny] spent the night drinking with the bar staff and the local customers until 4 a.m.," a source tells WHO. "He was in a good mood and they all had a big Danish party."
Adds a second source: "He only had three to four vodka-and-tonics and basically wound down from the gig. It was a relatively quiet night and Johnny was happy and relaxed."
"It is a smoking bar, so he was happy to stay for as long as he could," the source continues. "Johnny and the staff were drinking together. There were about 10 or fifteen people sitting in a group drinking and having fun. He was very nice and took a picture with some of the people in the bar. He was very friendly ... He talked a lot with the bartenders about the cinema and movies."
Depp was also photographed standing among a crowd of people and chatting with a blond woman. At one point, the woman is seen swigging champagne from a bottle while the actor smoked a cigarette. He was also seen holding the bottle of champagne.
Earlier in the night, Depp rocked out with his bandmates at an outdoor venue which once served as a state penitentiary.
The performance comes as more shocking allegations about his marriage to Amber Heard continue to unfold.
Just days before his show, Heard filed for a temporary restraining order against the actor, claiming he has been physically abusive throughout the entirety of their relationship.
A rep for Depp has not responded to WHO's requests for comment about the photos. In court documents responding to Heard's initial court filing, Depp's attorney Laura Wasser alleged that Heard "is attempting to secure a premature financial resolution by alleging abuse."
The actor is set to take the stage with his band in Romania on Monday to complete the European leg of his tour before returning stateside.
