Sabrina Bryan has won the viewers' choice vote to become the thirteenth contestant on ABC's "Dancing With the Stars: All-Stars."

"I am so excited. I'm getting teary eyed just right now," Bryan said today on "Good Morning America" when the results of the vote were revealed. "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."

Bryan, 27, earned the most fan votes online, beating out fashion commentator Carson Kressley (Season 13) and Disney Channel star Kyle Massey (Season 11). All three had been campaigning to win the thirteenth spot.

Bryan will dance with professional partner Louis van Amstel, who has appeared on seven seasons of the hit show.

"This is the first season I can knock myself out as a dancer, as a choreographer because she's so good," van Amstel said on "GMA." "From day one, we are going to knock even our own socks off."

Bryan, an actress, dancer and singer, is best known for being a member of The Cheetah Girls.

Competing in season 5 of "Dancing With the Stars," Bryan and partner Mark Ballas earned high scores - including a perfect 30 for their week four paso doble - and were heavily favored to win. Her elimination in week six of the season stunned the show's viewers and judges.

"For me, it's just incredible to have a second chance for my fans. They were just so supportive from the beginning to just stick behind me and rally the troops. …This is all about them. I am so lucky," Bryan said. "I feel like the stars are aligning and I get a second chance."

Bryan will compete against her former partner, Ballas, who is dancing with Bristol Palin, the daughter of former Alaska Gov. Sarah Palin this season. She joins Palin, actress Kirstie Alley, football star Emmitt Smith and nine other past contestants in the program's first ever all-stars competition, which premieres Monday, Sept. 24 at 8 p.m. ET.
