Gianfranco Randone (Italian pronunciation: [dʒaɱˈfraŋko ranˈdoːne]; born 5 January 1970), known by his stage name Jeffrey Jey, is an Italian-American musician and singer-songwriter, best known as the lead vocalist of the group Eiffel 65[1] (1997–2005, 2010–present).

He was also the lead singer of the groups Bliss Team (1992–1997) and Bloom 06 (2005–2010).

After Eiffel 65's reunion in June 2010, he toured[2] Italy and Europe with the band.

Jey's father moved his family from Sicily to Brooklyn, New York in 1972[3] and returned to Italy in 1984.

Due to his father being a musician and these twelve years spent growing up in New York he also became interested in becoming a musician due to all the influences throughout the city.
