"We can appreciate her being overwhelmed and inspired but we would've appreciated if she had done it from her seat." Alicia Keys is upset with rapper LIL MAMA for unexpectedly jumping up onstage during her performance with JAY-Z during their finale at Sunday's (13Sep09) MTV Video Music Awards. Lil Mama has since apologised for the stunt, insisting her "emotions were running high" and she was caught up in the moment.
