She said, "There was a time I met an actor I liked.  The French actress Léa Seydoux.  I happened to run into her at a department store when I was in France.  She was an actress I've always loved.  I was unable to ask if we could take a picture together and my face got red, so I said, 'Mom, what do I do?'  In the end, we took a selca.  My heart raced so much," making everyone laugh.

It's cute that even our goddess Krystal fangirls hard.
