'X Factor': Behind the scenes photos of your favorite performers

Rachel Crow and Bruno Mars

While "The X Factor" contestants spend most of their time rehearsing, rehearsing and more rehearsing, every once in a while they get to have a little fun. And sometimes the singers capture these moments and post them on Twitter.

Following are some of those photos. They include meeting big-time celebs, relaxing or just goofing off after a long day.

It sure looks like they're having a good time as they compete against each other for a $5 million recording contract.
