We're shaking in our dancing shoes to find out who the 13th contestant will be on Dancing With the Stars Season 15 All-Stars. And with just a few days left to vote (polls close on August 24), we're still wondering if the lucky final member will be Carson Kressley, Kyle Massey, or Sabrina Bryan.

Sabrina, aka one of Disney's Cheetah Girls, was seen at Good Morning America in NYC today (August 21), campaigning for last minute votes. The potential DWTS member was wearing a cobalt blue dress, super sparkly shoes (Mirror Ball much?!), and holding a "Vote Bryan DWTS All-Stars" sign.

As adorable as Sabrina looks, it's not set in stone that she will be the one back in that ballroom. Want to get your last minute vote in for Sabrina, Kyle, or Carson? Find out how here.

Dancing With the Stars Season 15: All-Stars will premiere on Monday, September 24 at 8 p.m. ET/PT on ABC. Check out the full All-Stars cast list here.
