The actor-rocker, 43, has filed a copyright lawsuit against the TMZ's bosses, claiming footage of him taking aim at Taylor Swift's music is an invasion of privacy, reported Billboard magazine.
The video hit the Internet earlier this week and led to a backlash against Leto from angry Swift fans, prompting him to issue an apology, which read: "The truth is I think @taylorswift13 is amazing + an incredible example of what's possible. If I hurt her or her fans my sincerest apologies."
Now, Leto claims the video featuring his outburst was stolen.
