why didnt rihanna jay-z and beyonce show up at the BET Awards '10

well i got your answer:
the reason why is because it was reported that jay-z beyonce and rihanna had got invites to come to the '10 awards but the reason why they didnt show up was because of Chris Brown's performance...! last year @ the 2009 MTV Music Awards Chris Brown was suppose to perform on the stage for the Michael Jackson tribute..but Jay-Z and Beyonce discuss with the MTV Productions to not let Chris Brown perform because of the incident with Rihanna...But this year's 2010 MTV Music Awards a producer of the MTV Music awards by the name i believe Neil had banned Rihanna Jay-Z and Beyonce from coming and for performing...!!! They actually boycotted to put it in simple words...like WTF!? Lets not live in the past...becuase while they still holding back...Chris Brown is making money and doing exce;llent in his life....so please get over the incident of Chris Brown and Rihanna... Last YEARS NEWS!!!!
