Tonight, the sold out Heart of the City Tour starring Jay Z and Mary J Blige, rolls through Atlanta. It will be on and popping at the Philips Arena as the sold out crowd sways to the soulful rhythms of The Diva, the Legendary Mary.

But the real action will take place after the concert when concert goers choose which mega Afterparty they will attend.

In one corner, you have AG Entertainment, which is billing its party at Dreamz ATL as the “Official” Afterparty with Mary J Blige, Lil Kim and Sean Combs hosting.

In the other corner is Jermaine Dupri, the music mogul and self-styled “Mayor of Atlanta” who is billing his party – hosted by newlywed Jay Z – as the Official Afterparty.

Who will win the battle of the Clash of the Titan After Parties? Well, the answer depends on who you ask.

According to a source up at Hot 107.9, the radio station initially refused to play JD’s ads because there was no signed contract guaranteeing that Jay Z would host the party. So I hear that a text message between JD and Jay Z was produced clearly showing Jay Z acknowledging he will be at JD’s party.

And JD recently posted a video of a phone call between himself and Jay Z on his YouTube channel.

So the jury is still out on that one, although the radio station has begun playing JDs ads. I also hear that Jay Z “owes JD a favor” so it figures that he would be at the party since he owes him a favor and all.
