Snooki, real name Nicole Polizzi, was snapped earlier today (16 September) during her final rehearsal ahead of tonight's show.
Wearing a black vest top, leggings and high top trainers, the mum-of-one is doing her best jazz hands and a little leg flick.
Sharing the picture on Twitter, Snooki commented: "Today's the day FINALLY! #DWTS."
Meanwhile, fellow celebrity dancer Jack Osbourne has received some support from his big sister Kelly as he gears up to hit the dance floor.
@JackOsbourne I love you so much I am so proud to be your sister its killing me that Im missing your Dancing debut good luck tonight Wacky!— Kelly Osbourne (@KellyOsbourne) September 16, 2013
Fashion Police host Kelly is currently in the UK for London Fashion Week so sadly won't see her brother's debut.
However, she tweeted: "@JackOsbourne I love you so much I am so proud to be your sister its killing me that I'm missing your Dancing debut good luck tonight, Wacky!"
