Kylie Minogue ''cried'' the first time she heard her duet with Enrique Iglesias.

The 'All the Lovers' singer has teamed up with the 'Hero' hitmaker on ballad 'Beautiful' and she says it was an ''honour'' to work with him.

She said: ''From my new album, 'Kiss Me Once,' this is the one and only true ballad. It's a duet with Enrique Iglesias and it's an honour singing with him. I actually cried the first time I heard it and I knew I had to be part of this incredible, romantic and touching song.''

The 45-year-old singer is also a big fan of Marvin Gaye's 'Sexual Healing', which she thinks is the ''ultimate sexy song''.

Discussing her Valentine's Day playlist, she said: ''What words can be added to this, the ultimate sexy song? Its magic never diminishes and it is still as hot as ever!''

When she's at home alone, Kylie enjoys singing other people's songs and is happy to give her private performances her all.

Continuing other songs on her Valentine's playlist, she said of Minnie Riperton's 'Lovin' You': ''Everyone get ready....who will hit those high notes? Love this song and no-one does it like Minnie.''

And of Bonnie Tyler's 'Total Eclipse of the Heart', she added: ''The ultimate power ballad. I love singing along to this and always, always include the 'air grab'.''
