Welcome to the semi-finals! Last week, the remaining Dancing With the Stars couples faced their biggest challenges yet as they prepared for a double elimination round. And now that they've made it all the way to the semi-finals, the competition is fiercer than ever as they all attempt to earn a spot in the finals — and get a shot at the Mirrorball trophy.

I know I've said this so many times this season, but these couples are so closely matched in both talent and likability that it's going to be impossible to predict who will be let go this week. Even with two dances apiece, it was more difficult than ever to find a weak link among them.

Unfortunately, Katherine Jenkins suffered a very noticeable misstep with only five seconds left in her second dance routine. It's unknown yet if the twinge she felt in her back will turn into a serious injury or just a fleeting pain, but she will be receiving medical attention after the show. Let's hope it doesn't greatly affect her chances of making it into the finals though because before that incident, her performance was absolutely flawless.

So who among the four couples will be the next to leave the ballroom and who will make it to the finals? We can't be sure, but perhaps the scores can be our guide. Check out the numbers below (from highest to lowest) and see if you agree with the ranking scale this week:

Maria Menounos and Derek Hough
