Best known for: The singles Love Me Or Hate Me and Nine2Five (vs The Ordinary Boys). She is one of the UK's best known female gime acts and the artist's career high came when she met rapper Jay-Z. After asking her to freestyle, he reportedly instantly signed her to the Def Jam record label, but she later left.

Lady Sovereign, better know to her loved ones as Louise Harman, who grew up on a Wembley council estate and spent a night in jail for spitting on a bouncer, is one girl who knows how to handle herself. Watch out BB housemates!
