Music producer Jermaine Dupri is joining Mariah Carey's management team.

When Gillian Lomax, who spent six years on radio KLOS's Breakfast with the Beatles, led her A Magical History Tour group to John Lennon's star on Hollywood's Walk of Fame next to Capitol Records on Vine Street on Oct. 5, she discovered that vandals had besmirched it with graffiti and scribbles, including a spotted toadstool, a smiley-face, "I love you," and "Blackbird... Rain was here."

Stopping by the Billboard studios before the single's Oct. 8 release, Paris Hilton told Billboard that her new record will include collaborations other rappers like Snoop Dogg, Flo Rida as well as producer Afrojack, who helmed "Good Time" and several other tracks.

The "art" in the phrase "album artwork" is rarely emphasized as much as when Lady Gaga is involved, and after meshing her body and a motorcycle on the "Born This Way," a Gaga sculpture gives birth to a giant blue ball -- the world, perhaps? -- in the official "ARTPOP" cover, which was unveiled on Monday (Oct. 7).

Not long after her "Saturday Night Live" gig this past weekend, Miley Cyrus took to "Today" Monday morning (Oct. 7) to debrief following "SNL," the VMAs and her spat late last week with Sinead O'Connor, one day before the release of her newest album, "Bangerz."

More than a year after the movie's premiere, the "Pitch Perfect" hit crowns its first Billboard airplay chart.
