Things got pretty chaotic when paparazzi caught up with Suicide Squad star Jared Leto and his team at LAX.
The 43-year-old Oscar winner was easy to spot on Tuesday afternoon, rocking florescent green hair for his role as The Joker in the action movie and he drew plenty of attention from photographers.

Swarmed by paparazzi upon return to Los Angeles, airport security guided Leto through a shortcut to his car, but before he could reach the vehicle, a member of his posse allegedly got into a scuffle with a paparazzo.
Photographer Fernando Biagi told ET that he felt his camera being pushed into his mouth, causing his lips to bleed. He then relayed this story to police, who were already on the scene and began questioning Leto's crew.
In the end, Biagi got an apology and no charges were filed.

Of course stars get flanked by paparazzi at LAX every day, and Biagi previously had a run-in with Kanye West.
"He doesn't like us," Biagi told ET. "He's getting better now, but he just plain doesn't like us."
According to RadarOnline.com editor-in-chief Dylan Howard, airline employees may tip off paparazzi to celebrity travel plans, giving them a leg up when it comes to getting the perfect shot.
"There are people that do work within those organizations that are moles that do provide that information," Howard told ET.
Paris Hilton didn't seem to mind the camera flashes when she touched down at the airport.

"I'm used to it," Paris said. "I've been doing this for so many years. It gets a little crazy sometimes, especially landing in foreign countries when there's like hundreds of them."
While other celebs complain about the photographers, paparazzi have a few pet peeves of their own. We found out one trick Justin Bieber does that drives them up a wall.
"He'll shrink down and run behind bodyguards and fans and stuff," photographer Erik Crown told ET. "We still got him."

Despite the inconvenience paparazzi might place on celebrities' lives, the other option is even more distasteful.
"The saddest day in a celebrity's life is when they walk off a plane and all the paparazzi are there and nobody chases them or takes their picture," photographer Malibu Ritch said. "That's a bad day."
