The 25-year-old singer, who was brought back to the competition for the first live show a couple of weeks ago, has reportedly been removed from the programme following background checks.

TMZ claims that producers discovered Jones was charged with two crimes in 2011, and that one of the incidents is alleged to have involved violence.
It is also alleged that Jones has outstanding warrants, and that there was doubt over claims that he was estranged from his father.
Jones was originally reported to have tweeted that he would no longer be on the show. However, the original message has since been removed.
He then retweeted a number of messages from Twitter users - most of which expressed support for him - which were also removed at around 11.30 ET (3.30 GMT).
Earlier on Tuesday (March 13), Jones also denied that he had told producers that his father had abandoned him, tweeting: "How can I be lieing nd I never said anything" (sic).
American Idol broadcaster Fox has not yet commented on the reports.
