After her infamous tumble at last year's Oscars, the 23-year-old actress took everyone by surprise when she slipped again on the red carpet at the 86th Academy Awards, reported E!Online.
"You know, I'm starting to wonder if this is a bit of an act," Leto said.
Leto, 42, who won the Best Supporting Actor for his role in 'Dallas Buyers Club' said when Lawrence came onto the stage to present an award, she found him and his family laughing.
"She said, 'What are you laughing at' But what she didn't know was that Ellen was on the side... making motions like 'Don't fall, don't fall,' and my mom and my brother are all cracking up," he said.
"I guess we don't have any manners. You can take them out of Louisiana but you can't take Louisiana out of them, right," he added.
