From bar mitvah ... to Broadway!

Sam Horowitz became an overnight sensation when his bar mitzvah dance routine went viral.

The 13-year-old was invited to recreate his performance live on "Good Morning America," right down to the sparkly shirt. Check out the video below:

Here's the original viral video, complete with the elaborate stage rigging with Sam descending from the ceiling:

Sam's mother Angela revealed that the routine was all his idea, and it was his dream from age 9. The routine was hard work though, Sam practiced his Christina Aguilera/Jennifer Lopez routine every Sunday for a month!

Who would've guess that he'd go from dancing at the Omni Hotel in Dallas to Times Square, just a few blocks from Broadway? Sam definitely joins Rebecca Black and Double Dream Hands guy in internet infamy!
