Identical twins John Grimes and Edward Grimes, aka Jedward, performed live at their autograph signing in Berlin, Germany much to the delight of their faithful fans. How many artists do that?

They are promoting their latest CD Planet Jedward and to be perfectly honest with you I do not know their music at all, but someone who I think the world of LOVES them so I’m doing this post for him. He should know who he is (do you C?).

I do know they got their start on the X-Factor in 2009 and despite Simon Cowell hating them (what else is new with Simon), they’ve gone on to have pretty good success (um hello, Sony Music?!). When they made it to the second rounds of X-Factor, Simon said of them: ”They’re vile little creatures who would step on their mother’s head to have a hit. Isn’t that speaking Simon’s language?

Double your fun with these pictures.
