Tulisa Contostavlos was left furious after six X Factor hopefuls romped with each other during the judges’ house stage of the show, according to reports. The antics are understood to have taken place between six wannabes at the complex where the N-Dubz star’s hopefuls have been staying in Mykonos. According to the Daily Mirror, Contostavlous refused to put through a band, calling them a “disgrace to the show”.  “She had got all the groups together and given them a stern pep talk, telling everyone they needed to act like professionals if they wanted to make the cut,” a source said. “This meant no boozing, no wild partying and certainly no extra-curricular bonding.”
