Flashback!! Derek and Mark dancing with Jonas Brothers
I found it!!!! Never saw but bits of it before – I’ve been wondering about this dance!! Silly me – search on Jonas and NOT Derek. 
Does anyone recognize the female dancers? One looks like Lacey, but this was before her time.
i love the Jonas Brothers, they are so handsome. I really like Joe Jonas in particular.
the Jonas Brothers is awesome, the sing well and they are very handsome. I love to watch their live concerts.
Phillipe I think so!she probably isnt back becuse of the prducers!
I was in my Jonas phase at the beginning of this season (and Joe happened to be my fave)! You could never imagine my excitement seeing my three fave guys (at the time) dancing together!!!
Also, I read somewhere that it was Derek’s idea for Joe to dance. Any clarification on that?
I remember hearing that too, although I have no idea how true it is.
the other pro is Inna, she was only in season 7
