Kylie Minogue could be following in sister Dannii's footsteps on reality TV after emerging as a frontrunner to join the British version of The Voice.

Minogue is in talks to star in the third series of the BBC reality TV singing contest, according to The Hollywood Reporter.

The publication cites an insider as saying the pop princess has been shortlisted to appear on the show, although she has yet to officially sign on.

If confirmed, the pop star will join Black Eyed Peas frontman will.i.am and crooner Tom Jones on the judging panel.

Minogue joined sister Dannii on Sunday's episode of The X Factor Australia in the mentoring chair, delivering a ratings hit for the Seven Network.

In 2012, the pop princess was rumoured to have been in talks with producers of Britain's X Factor to appear as a judge.

At the time, Minogue didn't rule out tackling a reality TV role in the future.

"It may only be a matter of time, who knows? Those shows are going to keep happening every year for the foreseeable future. I'm a fan of those shows," she told Britain's Sunday Express.
