Some say idle time belongs to the devil. This certainly seems to be the belief of Grammy award winning hip-hop mogul Jay-Z. The international superstar officially announced yesterday that he will headline a series of intimate performances as he takes a break from putting the finishing touches on his upcoming album, The Blueprint 3. Backed by his full band, the exclusive engagements begin July 3rd in Las Vegas and end on July 12 in Atlanta. Five dates in all have been confirmed thus far with more to be announced. Ciara will open for the Jiggaman on select dates. Ticket information is available at –BB
