"Dancing" Stars Tango with Burglar

According to people close to the situation, some dirt bags in Minnesota broke into a van belonging to Mark Ballas and Derek Hough -- they are in town to play a gig with their band Almost Amy at a charity event in Rosedale.

After a quick dinner, Mark and Derek noticed their van had been ransacked -- thieves taking everything from iPods to luggage and even their IDs and passports.

Now, they're already offering a $1,000 reward to anyone with info that leads to getting their stuff back. Hopefully the bad guys didn't touch the rhinestone onesies!
