'X Factor' contestants Maria, Brenda and Chenai were reportedly involved in a heated argument as a result of comments made during last week's live show.

According to the official 'X Factor' website, the row started when the contestants were watching a recording of their performances on the show.

Following Chenai's song, Simon Cowell, who is one of the judges on the show, said: "The other two girls in this competition are better singers.”

Chenai responded to this remark by saying: "They’re 15 years older than me.” This comment angered Maria and Brenda, who felt that the competition shouldn’t be about age.

According to the report, a researcher had to step in to end the argument, but the three are now reported to have settled their differences. Contestant Brenda commented: "We had a moment and now it’s all over and done with."
