Hailing from London and studying at the BRITS School, before finding fame as a singer, Jessie J wrote songs for the likes of Chris Brown and Miley Cyrus. She burst into the public conscious with her song 'Do It Like A Dude' where she talks about how she can measure up to men (in certain departments) and follow-up 'Price Tag' (about money or something) with imaginatively named US rapper B.O.B.
