The Walk On By hitmaker, who turned 72, was joined by family and friends for an intimate celebration at the Fontainebleau hotel in Miami Beach.
Warwick was presented with a blue birthday cake in the shape of a grand piano as Wonder sang Happy Birthday.
Her son, Damon Elliott, arranged the surprise musical gift and said, "No one knew that he (Stevie Wonder) was coming... I could not tell anyone. The hotel just knew that there was a pick up from the regional private airport."
