Lady Sovereign capped off 2005 by meeting with the American hip hop artist and CEO of the labels Def Jam Recordings and Roc-A-Fella Records, Jay-Z. This marked her foray into the American music scene. With Usher and L.A. Reid seated next to him, Jay-Z asked for one on-the-spot freestyle from Sovereign before offering her a contract with Def Jam. With the single "Hoodie", Lady Sovereign released her full-length debut, "Public Warning", on Def Jam in 2006. Lady Sovereign is the first non-American female to ever be signed to Def Jam Record Label.
