Do the Cheetah Girls Ever Really make it??

I never read any of the books, but I was wondering in the books do they ever make it. In the first movie, they perform and win the school competition and the record company that wanted to change them was like "Oh SNAP!!" but then in The Cheetah Girls 2, they were still trying to make it alluding to the fact that they have no record deal and still not have made it, so they thought they could make it with the Spanish Music Festival, which they won, but then in Number 3 One world, they were still dreaming and said they were trying to make it, especially in America, and they all got into the movie, so I'm just wondering do they ever make it, do they ever reach super stardom, is it they just keep trying? Or was it that they made it now after one world?
