X Factor champion Alexandra Burke and runner-up Ruth Lorenzo had to be prised apart after a bust up that took place during the X Factor tour.
An insider claims that the pair fell out after a dancer who Alexandra had had her eye on was spotted in a romantic embrace with Ruth.
The pair became best friends after appearing on the tv show last year and currently share a luxury London flat together.
Meanwhile a source in Alex's camp said: "Alex feels she is being singled out by Ruth and the others on tour because of her success. Their friendship is well and truly over. They can barely look at each other."
