Jay-Z Goes Ballistic

Jay-Z is man who usually keeps his cool...but not when crazed fans/little men-girls hop on his stage. Word is the Jiggaman went nuts after Lil Mama Lil Man Man hopped on stage and tried to "T-Pain" him during his performance with Alicia Keys at the MTV VMAs.

The NY Daily News reports Jay-Z waited 'til he got backstage to go "ballistic." He reportedly screamed at the producers about their poor security (remember, this happened after Kanye West's "I'ma let you finish" fiasco).

Sources say Beyonce calmed him down. Awww...
