Kylie Minogue was joined on stage by her little sister Danni in Melbourne this week to perform duet �Kids� together.

It is the first time the sisters have properly performed together in 20 years and they were delighted with response.

According to the Sun, Kylie said to the audience: �You all waited a long time for this to happen didn't you?"

Backstage Danni said: �When we were kids we'd dance around our bedroom singing into hairbrushes, so I guess we've had a lot of rehearsal leading up to this.

 �Kylie says in about twenty years we'll get an act together and work the Butlins holiday camp circuit".

Kylie will be in the UK from NYE to perform at Wembley Arena.
