Well, this is weird: TMZ has 3 minutes and 31 seconds of elevator surveillance footage that appears to show Solange Knowles, sister to Beyonce, physically attacking her brother-in-law Jay Z. The alleged attack took place in New York City's Standard Hotel at a Met Gala after party last week. The silent video shows Solange screaming at Jay Z, kicking at him, and hitting him with her purse (spilling its contents across the floor), all while Beyonce stands by without getting involved. Someone, apparently a bodyguard, holds Solange back, and Jay Z grabs her foot at one point as she kicks at him. It's not yet clear what started the fight, but TMZ says Beyonce and Solange got in a separate car from Jay Z when the threesome left the hotel. (More Jay Z stories.)
