Alexandra Burke's label, Syco Records, reportedly is mad at those leaking her new demos, "Perfect" and "Overcome", which hit the web earlier this week. "Label bosses are furious and everyone is in a panic," a source said as quoted by The Sun.

"Sony have spent thousands of pounds over the past few weeks investigating the sources of the leaks," the source revealed further. "We are now pretty close to nailing the people responsible but it's been a nightmare."

On whether or not the tracks will be included in Alexandra's upcoming debut album, the source stated, "The leaked songs are very rough early demos which were recorded months ago. We don't even know yet if they will make the final cut."

Alexandra Burke's not-yet-titled album reportedly is due for November release. In this record, the 2008 winner of "The X Factor" is said to work with the likes of Pharrell Williams, Timbaland, Akon, P. Diddy and RedOne.

Alexandra also got vocal coaching from Beyonce Knowles. "She's been giving me vocal advice and advice to make sure I'm keeping on top of my game. I look up to a lot and I can learn a lot from her," she said of Beyonce's contribution to her singing career.
