Which singer provides guest vocals on Flo Rida's 2009 single "Sugar"?

Wynter Gordon provides the guest vocals on Flo Rida’s 2009 single “Sugar.”

Released as part of Flo Rida’s second studio album, “R.O.O.T.S.,” the track combines Flo Rida’s rap verses with Gordon’s sung hook. The song was released in March 2009 and became the third single from the album, following the major success of “Low” and “Right Round.”

“Sugar” is built around a prominent interpolation of Eiffel 65’s 1998 Eurodance hit “Blue (Da Ba Dee),” especially its instantly recognizable vocal melody. That connection is why listeners sometimes identify the chorus with Eiffel 65, even though the new recording features Wynter Gordon’s vocals.

Gordon, a New York singer and songwriter, was credited on the track as “Wynter.” Her contribution helped give the song its bright, radio-friendly pop character, contrasting with Flo Rida’s rhythmic delivery. The stored answer is therefore the single canonical vocalist credit expected by the question.
