Jessica Simpson treated her Twitter followers to a very special treat on Thursday.
As part of the social media trend "Throwback Thursday," Simpson posted a vintage video of her high school performance of A Chorus Line's famous number "The Music and the Mirror."

In the YouTube video, a very young Simpson is still rocking the same blonde locks she has now, but gives her hair some major life with her impressive dance moves. The performance, which also includes high kicks and jazz hands, natch, gets big applause from the crowd.
The singer and former reality star, who is currently pregnant with her second child, is just the latest celebrity to cause a stir on "Throwback Thursday." A few weeks ago, Kelly Ripa shared a rarely seen photo from her 1996 Las Vegas wedding to Mark Consuelos.
