What female singer sang Jimmy Lightning in a Bottle as the finale song for movie which I also remember?

You're likely thinking of the song "Genie in a Bottle" by Christina Aguilera, which was featured in the 2000 movie "Center Stage."

While "Genie in a Bottle" is a popular song, it was never officially called "Jimmy Lightning in a Bottle."

It's possible you're mixing up the details, but if you can provide any more details about the movie or the song, I can try to help you identify it further.
