Jay-Z was furious after Lil Mama jumped onstage while he performed with Alicia Keys at the MTV Video Music Awards – because the performance took weeks to plan

The “Lip Gloss” rushed the stage unexpectedly towards the end of the superstars’ rendition of “Empire State of Mind” at the ceremony last week. Although Jay-Z tried to shoo the star away, Lil Mama even posed with the duo as the song came to a close.

“Me, personally, I would never do that. I would never have the nerve to do that. It’s just like, someone’s up there performing…” the “Run This Town” star told Hot 97 personality Angie Martinez on Wednesday. “We went through rehearsals, we did run-throughs and we worked really hard at the performance to put on a show for people and to interrupt that moment for us, you know, I don’t think that was the right thing to do.”

In fact, Hov feels the incident was just as inappropriate as when Kanye West ruined Taylor Swift’s acceptance speech earlier in the night: “I actually thought it was the equivalent of what Kanye did to Taylor Swift but nobody really talked about that because I’m not a little sweet girl from the middle of America. And I’m cool with her (Lil Mama) being excited and all that but you have to understand, people put in work to make that performance happen, that took weeks the planning of it. If you look at those screens, we had to go to Yankee Stadium to shoot that live, there was a lot of planning. To disrupt that was out of line. I was a little angry to be honest, but what do I do, fight Lil Mama?”
