Surveillance video has surfaced of Solange Knowles, a singer who's famous for being Beyoncé Knowles' sister, attacking Jay Z in a hotel elevator last week.
The altercation went down at a Met Gala after-party last week in New York.
Rock bands don’t get much bigger than Pearl Jam, but during their headlining set at Philadelphia’s Made In America Festival on Sunday (Sept. 2), the group added even more star power to their set, teaming with rapper Jay-Z for an encore performance of ’99 Problems.’
