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.
It was a rock and rap collision last night (Sept. 2) in the City of Brotherly Love when Pearl Jam were joined onstage by rapper (and festival creator/curator) Jay-Z for his 2004 smash hit ’99 Problems.’ Pearl Jam were headlining the final night of the first-ever Made in America Festival, held in Philadelphia, when this meeting of musical minds took place.
