Although Emma proved in a recent interview with MTV that she's memorized the lyrics to the infectious pop song, her memory fell short when it came to remembering the band members' names. When shown a picture of the guys and asked to identify them, she quickly pointed and yelled "Harry!" -- and that was it. (Perhaps this is because her bestie, Taylor Swift, introduced them?)
In the interview, Emma also chatted briefly about the upcoming "Spider-Man 2" flick, and expressed her love of hamburgers. Watch the video for some hilarious Emma moments, including an impromptu 1D sing-along.
