Sabrina Bryan won the viewers' choice vote to become the 13th celebrity dancer. She will dance with Louis van Amstel.
"I am so excited. I'm getting teary eyed just right now," Bryan said on "Good Morning America." "It was a fight ... we all three really wanted it. I'm the lucky one with some amazing, incredible fans that have really stuck behind me."
The "Cheetah" girl from season five earned the most fan votes online to take the coveted spot, beating out Carson Kressley and Disney Channel star Kyle Massey.
The other competitors, who were announced in July, are Bristol Palin, Helio Castroneves, Kelly Monaco, Shawn Johnson, Apolo Anton Ohno, Melissa Rycroft, Kirstie Alley, Drew Lachey, Gilles Marini, Emmitt Smith, Pamela Anderson and Joey Fatone.
In season 5 of "Dancing With the Stars," Bryan and partner Mark Ballas were heavily favored to win, but they were eliminated in week six, stunning viewers and judges.
The 15th season of "Dancing With The Stars" premieres on Monday, Sept. 24 at 8 p.m. ET/PT.
