We thought we knew all there was to know about this past season of Dancing with the Stars, especially as far as Cameron Mathison was concerned.

Turns out, though, that the All My Children hunk needed an assist from Mavericks owner Mark Cuban about halfway through filming.

Cuban rushed in to help Mathison when the actor strained his hip (Mathison suffers from a childhood disease that endangers the use of both hips) while performing on the show.

"Mark was such an amazing help," said Mathison. "He doesn't tell anyone he's doing these things. He just does them. He put me on the phone with the trainer for the Dallas Mavericks and [the trainer] told me what to do to test the hip, to see what kind of injury it was. It wasn't serious. But I was really worried."
