On Thursday, Emma Watson was blushing and embarrassed with the "post-traumatic stress" of her last visit to Jimmy Fallon's show.
Watson and Fallon told viewers how the last time she was on The Tonight Show was the first time the two met.
"Before we even start the interview I just dove straight in there with, 'I love that Halloween candy thing that you do,'" said Watson, laughing. "And there was just silence."
Fallon jumped in to tell the story. "You go, 'When you get kids [and] you trick them' and I go, 'That's Jimmy Kimmel.'"
"I died inside," Watson said remembering her mistake. "You turned bright red," said Fallon.
The Circle actress said she appreciated Fallon letting her leave the room and re-enter to start the interview over again, but said she did like the vibe for the rest of the show because "Everyone was in hysterics."
"I get that all the time," Fallon reassured her of the mix-up.
In fact, Fallon recently told The Hollywood Reporter that a group of fans also mixed him up with the ABC host this past year.
"I took some selfies with some fans and talked to them for almost 20 minutes one morning," he said. "As I turned around to continue my walk I heard them scream. 'OMG! Jimmy Kimmel!'"
