John Mayer ended an already emotional tour-opening show at Milwaukee's Marcus Amphitheatre on a high note when he reportedly dedicated the last song of his set, "A Face To Call Home," to on-again off-again girlfriend Katy Perry, calling her "my face to call home." Hard to believe that Paris Hilton is signed to the record label that built its empire off street-bred artists like Juvenile, B.G. and Lil Wayne, but in May it was announced that the Hilton heiress has joined Cash Money, and Birdman couldn't be more excited. "She got a record we're about to come out with and she's very talented. You know she's already somethin' special as an entrepreneur and everything that she do," Jay-Z told a fan on Twitter that his brand-new release Magna Carta Holy Grail may only be his 4th best album, referencing his 1996 debut Reasonable Doubt, 2001's The Blueprint and 2003's "The Black Album."
