Jennifer Lawrence  took the stage to present the award for best actor at the Oscars in LA on Sunday night, but before she got to announcing the nominees, she had a laugh and asked a few questions toward the audience while at the microphone. What was that all about? Well, Matthew McConaughey  shared in the press room later that Ellen DeGeneres  was to the side of the stage making tripping motions, since Jennifer has a history of falling in the spotlight — and even fell on the red carpet  on her way into the show! Jared Leto  apparently saw Ellen from the audience and was laughing himself, prompting Jennifer to address him by saying "Why are you laughing? Is this funny?" before she continued on with her presenting duties.
