The star, in Australia to promote her new album, was asked if she would like to get married by a local radio show.
She replied: 'Yeah sure, if someone will have me.'
Asked how she will create her wedding dress, she replied: 'That will be a pain in the ass won’t it.
'I'm just exhausted thinking about it, well no-one will ever see it.
'I'm not going to let anyone photograph or see my wedding, it’s going to be top secret.'
Discussing having a baby, she said: 'Yeah, and I would keep all of that for me, for me it’s all about the music, the other things, that’s family, I like to keep family separate.'
The star’s on/off boyfriend Luc Carl is believed to be with her in Sydney.
She performs at Sydney’s Town Hall on Wednesday night.
