BGUK_1161881 - ** RIGHTS: WORLDWIDE EXCEPT IN UNITED STATES ** Los Angeles, CA - Jennifer Lawrence caught trolling pal Emma Stone during Jimmy Kimmel's Oscar opening monologue. The Hunger Games star was spotted pointing at Stone and laughing uncontrollably as Kimmel cracked a joke about last year's Best Picture gaffe where Stone's movie La La Land was mistakenly announced as the winner. Stone tried to keep a straight face as the camera panned to her - despite Lawrence, who was sitting next to her, sticking her finger in her face and then laughing. The moment has since been turned into a GIF and is all over social media. *BACKGRID DOES NOT CLAIM ANY COPYRIGHT OR LICENSE IN THE ATTACHED MATERIAL.
