The 29-year-old star said that although she has very little in common with the Toxic hitmaker, as she hates singing in public, she was also very excited and so decided to play along with the fan.

This has happened three times with the Pirates of the Caribbean star and she has also been mistaken for other celebrities like Kate Winslet and Natalie Portman, she further added.
