John Mayer is addressing rumors on that his song, "Paper Doll" is a response to his ex - Taylor Swift's song "Dear John," Appearing on the Today show to promote his new album, Paradise Valley, the singer-songwriter said "Songwriters write songs because of people, about people. Anything someone else wrote is their reception of a song. I don't get involved in it. It's none of my business," Jay-Z's bold marketing campaign for "Magna Carta Holy Grail" paved the way for a Fourth of July brimming with high-profile buzz, but critical reception to the album has been somewhat mixed.The New York Times claims "Grail" is filled with "ups and downs," while The Los Angeles Times feels it's "full of empty boasts." USA Today, on the other hand, awarded the album a perfect four-star review. According to her mom Dina, Lindsay Lohan will be leaving the temptations of Hollywood behind for good by moving back to her native New York after she completes her current stint in rehab later this month.
