How ironic. Amber Heard -- who filed domestic violence charge against husband Johnny Depp -- was once arrested for assaulting an ex-girlfriend herself.
Gossip tabloid TMZ reports that Heard, 30, was arrested in 2009 following an incident with ex-girlfriend, artist Tasya van Ree, 40, at Seattle-Tacoma International Airport.
TMZ -- Amber was arrested and booked for misdemeanor domestic violence. Her mug shot was taken and she appeared in court the following day.
TMZ has obtained audio of the court hearing, where the prosecutor declined to move forward with the case -- we're told because the women both lived in California. The judge told Amber she was not off the hook ... prosecutors could reconsider and refile within the 2-year statute of limitations.
Amber thanks the judge and leaves the courtroom.
