Margot Robbie stopped by Jimmy Kimmel Live! on Tuesday night, but she really should have been on the Hogwarts Express. What started out as a regular interview quickly turned into a hilarious and embarrassing moment for the Legend of Tarzan actress [1] when the host revealed a throwback photo of her that one of her best friends sent in. In the snap, a 13-year-old Margot is drinking a cup of tea while reading a Harry Potter [2] book in bed. But while that could have been enough to make Margot blush, she took things a step further and actually revealed that the glasses she's wearing in the photo are completely unnecessary. "I'm wearing glasses, which I didn't actually need," she explained. "I have 20/20 vision, and I lied to get glasses so I could look like Harry Potter. They're not even cool ones. They're, like, ugly glasses. I went to the optometrist and I was like, 'I can't see that. Ow! My eyes hurt!' My mom's like, 'Do you really need glasses?' I was like, 'Yes, I do!'" Watch the funny moment above, then check out her recent red carpet appearance with Alexander Skarsgard [3].
