And of course there are cameras along for just about every moment of those practices. They often catch things some people would rather the world not see, but not Kate.
"This is Kate Gosselin," said professional dancer Tony Dovolani. "There is really no hiding for her. She's gonna tell you how it is right from the start."
The 35-year-old former reality star says she doesn't mind that scenes of her bickering at rehearsals with Dovolani aired.
"The cameras caught it and the truth is its life. We all have those moments whether cameras are on us or not," said Gosselin. "The truth is I was actually appreciative of the fact that, that is the true pressure that we're all under. Obviously there is going to be moments like that and I don't really care."
Gosselin and Buzz Aldrin were at the bottom of the judges' leaderboard last Tuesday, but viewer votes saved them.
"I am so grateful to everybody who voted," said Gosselin. "Please continue to vote because we all know that my dancing isn't keeping me here."
The remaining 10 couples dance again Monday night at 8 p.m. on ABC7. The celebs will be tackling the Quickstep, Waltz and Paso Doble.
