R+B newcomer Cassie confesses she's prone to temper tantrums and freaked out recently when she wasn't given a cup of tea at a concert. The 19-year-old Me + U singer - real name CASSANDRA VENTURA - admits she can be a diva and frequently gives her manager "an earbashing". She says, "(I last had a tantrum) probably yesterday. I really, really needed tea yesterday and no body brought me any, so I was like, 'How many times do I need to ask for tea? I'm about to go on stage!'."
