James Franco allegedly attacked a paparazzo at Lana Del Rey's concert in Los Angeles on Friday (17.10.14).
The 36-year-old actor reportedly tackled the camera man to the floor at the Hollywood Forever Cemetery following the 'Born to Die' hitmaker's performance.
The 'Spring Breakers' star was caught on camera running away from the snapper, who was left lying the grass, with a massive smile on his face.
A source told E! News: "Franco ran head first into the photographer and tackled him football style."
It is not known what the altercation was about but the paparazzo is allegedly looking for compensation as he filed a report with the Los Angeles Police Department office on Saturday morning (18.10.14).
The unidentified photographer has claimed his camera equipment was damaged in the scuffle and he is now suffering from a minor back injury, according to TMZ.
Meanwhile, James and Lana, 29, have sparked rumours they're dating after they were spotted attending a screening of his movie 'Child of God' in New York City in August, and then she joined him for an intimate after-party at the Tribeca Grand Hotel.
A source said at the time that James, who was previously linked to Ahna O'Reilly and Erin Johnson, thinks the singer is "fascinating" and their friendship is on the cusp of turning romantic.
The insider added: "They've been hanging out and talking a lot."
