The "Hunger Games" star says she embarrassed herself in front of the 73-year-old actor and "Star Wars: The Force Awakens" director Abrams, reported Female First.
"I probably humiliated myself more than ever before. I never assume anyone knows who I am, but when I spotted Harrison Ford and JJ Abrams, I was like, 'It'll be fine, we're all co-workers, right!'
"So I went up to them and started dancing like an idiot and the whole table just went quiet and stared at me. I realised while I am dancing that they had absolutely no idea who I was so I just turned around and walked back to Jack (Whitehall) dying of embarrassment," she said.
