Here's an article on MTV that I found, mainly about Usher going into acting, but it mentions how he aspires to be like Will:

Here is the important part of the article:
Ultimately, Usher reveals, he'd like to establish the kind of mainstream music/movie career currently being trailblazed by one of Hollywood's biggest stars. "There's probably only one ... Will Smith," he said, beaming with admiration. "You look at the overall build of his career ... I'd love to have something similar to that, man."
I like how he says, "There's probably only one...Will Smith," and how he wants the same overall build of his career. I don't know if he can do it, but it is nice to see that he recognizes how successful he is, how he is really the only one to be doing what he is doing.
