Beyonce Knowles’s diva demands were finally fulfilled. The singer reportedly refused to walk to her car in the cold after rehearsing for US new President Barack Obama’s pre-inauguration concert. A source claimed that she went crazy when she learnt she’d have to walk four blocks away to find her car as some streets were closed due to security issues. Finally, US Secret Service decided to allow her driver to come and pick her up. In other news, Kelly Rowland dumped Beyonce’s dad as manager.
