We're so glad that Demi Lovato and ex Joe Jonas seem to be working at getting their friendship back on track!

And they seem to be using twitter as their chosen tool of communication. (Well, at least its something!)   

According to Hollywoodlife.com, the pair recently joined up for a benefit concert and shared with the world, via twitter of course, how happy they were to be singing together again.

Joe tweeted; “Pumped for the show tonight with @ddlovato who's coming???!?!"

And Demi later replied with;  "@joejonas you sounded so great tonight! One show down, few more to go. Just like old times! Haha!"

To which Joe replied;  "Fun show tonight with @ddlovato what do you say we do some more D??"

Don't you just love Twitter?!
