Jana Kramer and Gleb Savchenko
Jana Kramer and Gleb Savchenko are one of the sexiest couples in the mix this season. Even so, dancing is a tough gig and Kramer has already injured her ribs. Previously, Kramer told People: I've had some minor injuries here and there but nothing ever like this. At times it can hurt to even breathe. But I don't want America to think I'm a baby. I've pushed myself so hard and I'm going to keep pushing, but my body is just pushing back right now. She's also struggling emotionally as she deals with the separation in her marriage. (ABC/DWTS)
