Beyonce Knowles has been lambasted for not turning up at last night's (20SEP06) Music Of Black Origin (MOBO) Awards. The singer picked up three awards on the but her absence and failure to pre-record an acceptance speech was met with boos by the audience at London's Royal Albert Hall. Her boyfriend SHAWN 'JAY-Z' CARTER, who was named Best International Male, was another no-show. Reports suggest Knowles was deterred by former DESTINY'S CHILD bandmate LeTOYA LUCKETT - they have barely spoken to since Luckett quit the girl group six years ago (00) - and potential love rival Rihanna. Both performed at the show. A source tells London newspaper the Evening Standard, "Jay-Z signed Rihanna to his label and the rumour is they got a bit too close for Beyonce's liking." Best Group THE Black Eyed Peas and Best Reggae Act Sean Paul also snubbed the ceremony.
