Madonna as never seen before... dancing casino!

Madonna dared... of course! What hasn't Madonna done in this life other than "dare"?

Well, you should know that the Pop Diva has posted a video on her Twitter account, in which she is seen dancing "casino" to the rhythm of Isaac Delgado's music.

At times he seems to lose his rhythm, or never find it, but hey, it was his birthday, right?

And he enjoyed it very much.

What do you believe? He did good?
