Jay-Z may have 99 problems, but winning over Glastonbury fans ain't one. The New York rapper, headlining the annual mud'n'music fest this past weekend, responded to comments by Oasis guitarist Noel Gallagher (who famously said this spring, "I'm not having hip-hop at Glastonbury. It's wrong.") by, well, taking a page from the Brit rocker's music book. Strapping on a guitar wasn't the weapon of choice for Amy Winehouse; when an audience member grabbed at her beehive, the recently-hospitalized singer threw a punch. Her violent response was not sanctioned by Nelson Mandela, we're guessing, although he may have a soft spot for "Blake Incarcerated." And while Jennifer Aniston had her own personal paparazzi moment this weekend, when she was spotted snapping photos of her rocker boyfriend John Mayer performing in London on Saturday night, she was not the shutterbug who captured Winehouse's Glastonbury altercation on film. Let's hope that Beyonce passed along some sage advice to Winehouse while the two singers cheered from the VIP section during Jay-Z's set.
