Lil Mama Crashes a Performance by Jay-Z and Alicia Keys at the 2009 MTV Video Music Awards

CNN - Kanye West's disruption wasn't the only one the evening offered, Wilson said.

During a performance by Jay-Z and Alicia Keys, rapper Lil Mama rushed the stage.

Wilson said that from his vantage point in the audience, the female rapper, who also serves as a judge on MTV's "America's Best Dance Crew," was neither expected nor wanted as part of the performance.

The stars' behavior might have long-lasting consequences, Wilson added.

"I wouldn't be surprised if MTV banned alcohol [at the event] next year," he said.
