“Billy Bob definitely, absolutely did not have an affair with Amber,” says the source.
The accusation comes as a new photo claims to show Depp’s butchered finger alleged injured during an altercation with his estranged wife in March 2015 while they were living in Australia.
After the injury, Depp, 53, allegedly dipped his finger in a jar of paint and wrote various messages on a mirror including “Billy Bob” and “Easy Amber.”
Heard and Thornton, 61, starred together in the still-unreleased thriller London Falls. The actress also adamantly denies having an affair, according to TMZ.
