Mel B spats with Simon Cowell over her last act Andrea Faustini

Melanie Brown, who fears that Simon Cowell is trying to oust her last act in the competition Andrea Faustini, has spat with the 'X Factor' boss, it has been revealed.

A source said that the 39-year-old singer, who is fuming that Cowell won't stop talking about Faustini, is out to get her revenge and so Cowell should be worried, the Daily Star reported.

Show supremo Cowell, who still has two acts remaining in the competition, said that he thinks Faustini's peaked because it's the same thing week after week, the same silly faces.

Cowell continued that he thinks it'll be Fleur, Ben and Lauren would be in the final, suggesting that Faustini won't make the final.
