Dannii Minogue "No Longer Serves a Purpose"

Dannii Minogue could be fired from her job as an X Factor judge - because she "no longer serves a purpose".

The former Aussie pop star - sister of Kylie Minogue - won't be asked to return to the ITV show next year, reports Britain's Heat magazine.

A source tells the publication, "Dannii was brought in initially to be the younger counterpart to Sharon, but since Cheryl Cole arrived, she has replaced Dannii in that role and become much more popular."

Dannii is also said to be involved in a rift with fellow judge Simon Cowell.
