"I'm so excited! I think it's going to be so fun," Brinkley, 65, said before adding, "I literally don't know how to dance. Seriously, it's true… I really don't have the moves. So I'm really excited to learn with the pros. It's a wonderful opportunity for me."
"I think whoever I get has his work cut out for him," she continued. "I think they need to give me a really good one because I need a lot of work… All of the dancers on the show are incredible, really amazing."

Brinkley also expressed that she had "always wanted" to compete for the mirrorball trophy, but had "conflicts with contracts that wouldn't allow me to take that kind of time."
"I just have a slot here," she said, before jokingly adding, "I'm guessing I'm not gonna be around all that long. [laughs]…Everybody's been doing dance lessons. Everybody's, like, already got the moves."
While she said she hasn't started taking any dance lessons in preparation, Brinkley has her own game plan if her moves don't impress the judges.
"If I can't do it with my feet, I'll distract them with my face!" she said with a laugh.
