The X Factor's Tabby Callaghan is growing close to Kelly Osbourne, according to the Sunday Mirror.

Tabby, who was managed by Sharon Osbourne during his time on the show, has become close to the Osbournes, since he stayed at their home with the other '16 to 24 solo' finalists.

"Tabby is everything Kelly likes in a man," a source told the newspaper. "He's a rocker, he's cool, and is off-kilter.

"Ever since Tabby stayed at the Osbournes they have been close. Tabby's romance with long-term girlfriend Anna Leask - the mother of his six-month-old son Illan - has been on the rocks since appearing on the show."

Tabby and Anna were reportedly involved in a fight last month. Tabby later admitted that Anna had been feeling lonely since he joined the show.
