Changes are coming to Dancing with the Stars. So is Anna Demidova.

The part-time model was born in Moscow and has accumulated a number of titles throughout her successful career. They include International Grand Ball 10 Dance Champion; USA Dance National Standard Champion; and multiple-time U.S. Youth International Standard Champion.

She'll be aligned with a celebrity when the series premieres on September 22.

Meanwhile, executive producer Conrad Green has confirmed that the competition will, indeed, bump up its number of contestants to 16. He told Entertainment Tonight:

"This is going to be our biggest-ever cast. We are going to start big, and then about halfway through, we are going to do three double eliminations back-to-back. The middle of the season is going to be brutal when half of our cast goes in three weeks."

Regarding casting rumors - is Ashley Hamilton really among the competitors? - Green remained mum and mysterious.

"If people get in the press and say, 'I am on the show,' even if they are not, what can you do? I think our celebrity show is the one that most people want to be on because they realize it isn't degrading or demeaning in any way. You learn a new skill, and it is a wholesome family show."
