What does The Joker do when he's not trying to save the world as part of the Suicide Squad or tormenting Batman? He's causing trouble for TMZ and slamming the musical talent of mega-star Taylor Swift. It's not yet clear if Jared Leto has completely shivered off his Clown Prince persona, but in a video recently leaked by TMZ, the Academy Award winning actor slammed the pop princess. And now, he wants some retribution for all the woes it has cause.

Jared Leto has filed a lawsuit against TMZ for posting the purloined video to their website earlier this week. In the stolen footage, Jared Leto insults Taylor Swift in a manner befitting DC Comics most iconic villain. Watching the video, it seems as though he knows he has an audience. But Leto is now claiming that the Hollywood insider website had no business posting his 'private' takedown of the popular singer.

If you haven't seen the video, we can't show it to you here. Dare we catch the ire of The Joker himself. But it shows Jared Leto listening to Taylor Swift songs, hoping to catch some inspiration for his next 30 Seconds to Mars album. He and his bandmates want to write a hit. Perhaps the key lies within her latest album titled 1989. You can watch the full clip here.

After listening to songs such as 'Welcome to New York', 'Blank Space' and 'Style', Jared Leto decides this music was not made for him or his band. And this is where he gets in trouble. After discussing some elements that might fit into his band's oeuvre, he exits this line of thinking and offers up this Joker-inspired mantra.

"F-ck her, I don't give a f-ck about her, it's whatever works best for us."

The actor later apologized. Here's what he had to say in a statement on his personal Twitter page.

"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."

In suing TMZ, Jared Leto claims that the videographer who sold the footage to the gossip website did not have the right to do so. The footage was sold for an alleged $2,000. The actor goes onto claim that the video was shot inside his home. And because of that, it rightfully belongs to him. He goes onto say that his representation alerted TMZ well in advance of them uploading it. He warned them that they did not have the legal right to be publicly displaying the footage. But they did so anyway.

30 Seconds to Mars's Sisyphus Touring company filed the lawsuit. It was accompanying by a statement from Jared Leto himself. His hope is that the lawsuit will help encourage more people to 'stop trafficking in stolen goods'. TMZ has not responded to the lawsuit. You can check out Jared Leto's apology tweet here.
