Gemini's Twin is a fictional R&B/pop music group created in sketches on the American television comedy program Saturday Night Live. The sketch featured Maya Rudolph and Ana Gasteyer as members of a "famous" singing group that parodied Destiny's Child. The two would incorperate hip-hop slang into their conversations in inappropriate ways, often misusing intellectual words or making up new words altogether. ("It's time to get musicational!" "Our music comes from a very emotionary place.")

A celebrity (often that episode's host) would often appear as the current third member of the band. Such third members have included Cameron Diaz, Lucy Liu, Britney Spears, and Jennifer Lopez. This was a jab at the infamous turmoil and frequent membership changes in Destiny's Child.

In one memorable sketch the real members of Destiny's Child appeared as former members of Gemini's Twin who had been kicked out of the band. They were there to introduce the new band they had formed on their own, but they got into an arguement with their former bandmates that led into a sort of sing-off. This culminated in Michelle Williams, who was lurking in the background of the confrontation, pushing her way forward and belting out "I'm just here!" (This was essentially Williams making fun of public speculation that she was hired into Destiny's Child simply to round out the band but made no real contribution.)
