British pop-duo: George Michael and his best friend Andrew Ridgeley.
Wham! was an English musical duo formed by George Michael and Andrew Ridgeley in the early 1980s. They were briefly known in the United States as Wham! UK due to a naming conflict with an American band. George Michael has recently hinted that he would like to reunite with Andrew Ridgeley as Wham! for a one-off concert in 2015.
