NEW YORK (AP) _ Grammy-winning rapper Jay-Z has been charged with attacking three people, including two he allegedly bashed over the head with bottles and a record executive he allegedly stabbed in a nightclub brawl.

The 29-year-old rapper, whose real name is Shawn Carter, was released on $50,000 cash bail on Friday after he was arraigned on three counts of assault.

Lance ``Un'' Rivera, 33, was allegedly attacked by Jay-Z after a fight broke out among several guests during a party Wednesday night. Rivera, founder of Untertainment Records, was treated at a hospital and released.

The other two incidents allegedly occurred last week and in 1998.

Harvey Slovis, Jay-Z's lawyer, denied that his client attacked anybody.

``He was not involved in it,'' Slovis said. ``He didn't do anything.

``When you're successful, everyone comes out of the woodwork with these allegations. There's no way these things happened.''

Last year, Jay-Z portrayed himself in the semi-autobiographical short film, ``Streets Is Watching.'' The film's soundtrack included the hit single, ``It's Alright.'' Jay-Z's ``Vol. 2: Hard Knock Life'' won best rap album at this year's Grammy Awards.
