The 26-year-old singer has just appeared as a cartoon version of herself in a special episode of the American cartoon sitcom, 'The Simpsons' and it is an experience she will never forget, reported Showbizspy.
"I was more nervous than I have ever been because I am such a fan of the show and everyone on it is so talented.
"At times they made fun of me and I made fun of them but that is how I am professionally anyway so that was fine," she added.
