"Baby I'm a Star" is a song written and recorded by American musician Prince from his album Purple Rain.
It was also in the original cut of Tim Burton's 1989 film Batman, used in the Joker's parade scene.
However, when Prince agreed to compose the Batman soundtrack, he opted for the song to be replaced by "200 Balloons" (of which when rejected, turned up as a B-side on "Batdance") and later with "Trust", the latter of which seemed the most musically similar to "Baby I'm a Star", for both songs are about the same length, have a similar drum loop and lyrical pace.
"Baby I'm a Star" is often played in sequence with "I Would Die 4 U", the track prior to it, on Purple Rain.
