If you watched Dancing with the Stars last night, you no doubt saw the blow-up between Derek Hough and Jennifer Grey that occurred during rehearsals. But does this mean there's trouble ahead for the frontrunners? Not if you believe them.

According to Derek, the tiff happened when Jennifer was having trouble trying to do something basic: Walking. "I was like, just walk in a straight line. 'I can't do it, I tell you!'" Needless to say, things got a bit heated. "I rarely, rarely, rarely lose my temper," said Derek, before adding, "I've seen this one lose her's before. Scary!"

Still, Jennifer says she's only human. "We both — I'm very sensitive, and he was just frustrated. So what? Human beings. Whatever. It's not that big of a deal. We're like caged animals." OK, Jennifer, if you say so.
