Jay-Z had a grand re-opening of his nightclub last night and it was billed in advance as the debut of a post baby Beyonce, but she was a no show. Maybe they are trying to figure out how this whole post baby body thing should work? Hide a little longer and then just say it "fell off." So, Jay was out by himself although as you can see above, one of the richest men in the world, Warren Buffett stopped by to show Jay-Z the stain in his tie. Dairy Queen will do that to you everyday. He should know that by now though since he owns it.
